You should bug WD about putting the 23.976 back again that has been removed since 1.04.17 (?).

also @ sinker442

I am putting my issue on hold for a few days. Busy with life and the Superbowl weekend stuff.. The issue about streaming VC-1 m2ts files…

Sorry if off topic, but the Live+ drove me into this:
Did some work to figure out how to get my Win XP PC to act as a UPnP/DLNA Host. After some work, got Windows Media Player to host files, but it refuses to host .m2ts files (it will play them, but will not host them). Also learned that Boxee can not UPnP host either. Found a free beta DLNA Server tool for cross-platforms, looks very promising, and the developer is actively working on newer releases as they go. I think this tool can be a DLNA Host, will find out later. (UPDATE: Yes, it is a DLNA Host) Their website is freakishly well done for a free tool. They will likely switch to a paid product in the near future. It is called TVMOBiLi. Similar to XBMC, this UI could also be installed into that future HTPC that we briefly talked about. -Later.

With the Live using the "media servers" option (UPNP/DLNA), I can stream the Dark Knight 1:1 .m2ts rip (VC-1) perfectly, wired from my laptop --->router --->WD Live.
However other people have different setups, and have problems.

NFS is only possible with B-rad's firmware.
Also changing the container from .m2ts to .mkv won't help (those 1080p .mkv you 've read about, that play without problems, are lower bitrate reencodes you can download from the internet, not 1:1 bluray rips)

“Hello CD listeners” -a Tom Petty thing….

I have a Live+ with 1.03.49 (posting in the non-plus thread only because this issue was covered here before)

In a previous post or two, I reported that I was able to playback BR.m2ts files, but with some problems. I used both methods available (Method #1) SMB/CIFS Network Shares and (Method #2) UPnP/DLNA Media Players.

Method #1 Network Shares: resulted in video/audio stutter only when playing m2ts files that had high bit-rates. Lower bit-rate m2ts files played OK. I am happy to report that this stutter problem is now gone. The problem disappeared after (#1) updating firmware of my Linksys router (#2) updating firmware of my Ready-NAS (#3) connecting/reconnecting lots of network cables. It is my guess that the problem was fixed because of action #1. I had some stutter on MPEG-2, AVC and VC-1. Now I do not. All is good.

Method #2 Media Players: I am still unable to playback m2ts files if they are VC-1 CODEC.“Unable to play the selected file. Please see the user manual for a list of supported file formats.”

In order to troubleshoot this further, I used 2 media player clients (WDTV Live+ & PS3) and 2 media servers (Ready-NAS & PC running TVMOBili v1.4.0.2825). It is unknown if TVMOBili 1.4.0.2825 ( a beta) has problems with VC-1. Using the different combinations of Media Players and Media Servers –and- 4 different .m2ts movies resulted in 24 results to report. The results of these tests are best seen in an Excel worksheet that I created. If you have Excel and would like to see it, please send me a PM and I will send it to you via e-mail. Later today or tomorrow, I might screen-shot it and post the picture here or might get the Excel file hosted somewhere so that anyone can quickly dl the file (without having to send me a PM).

Outside of the test results, I also re-muxed Batman Begins (a low bit-rate VC-1) and removed all audio and PGS title sets, and still could not get the Live+ to play it. I also attempted this while removing my Linksys router from the equation and separately also removed my network switch ( a 10/100/1000 switch) from the equation. This leaves (kind-of sort-of) only my network cables to be suspect. Can my cables prevent playback of m2ts VC-1 via UPnP/DLNA and not be a problem if via SMB/CIFS…? Sounds silly.

I have tried m2ts VC-1 files that were remuxed and other VC-1’s that are an exact copy (untouched) of the BR disc (i.e., The Dark Knight). Please note that all of my m2ts files are from disc’s in house, and none came from internet sources. I understand that streaming 1:1 copies of m2ts is an extreme test of the network and the Live+, but why is it that I am unable to start playback of only VC-1 stuff?

One suspect thing sticks out… my PS3 (with recent firmware from Dec 2010) is also unable to playback the VC-1 files. I saw some reports that stated this used to be a problem, but was fixed in late 2008 via fw upgrade & enabling a function (a WMA thing?) in the UI. Why is it a problem for me now? Is it a problem for others too?

I have seen other reports of VC-1 issues on other media player platforms, but I do not have any thing to post here that helps me/you understand any better. I am hoping someone other than Sinker442, can duplicate this problem or confirm (again) that you are not having this problem.

Any replies are very much appreciated.

UPDATE: playback problem of VC-1 encoded m2ts files via WDTV Live+ DLNA is not associated to the Live (thanks for your assistance Kelson, Hydrogin and sinker442). The problem has been isolated to the firmware of the NAS I am using. The problem has been fixed with a new firmware just released (Feb 2011). The firmware is ReadyNAS NV+ ReadyDLNA version 1.0.19. There is also a fix (using upcoming/new firmware version 4.2.16) for newer ReadyNAS devices such as the ReadyNAS Ultra-6+.

I recently got the Live+ and have installed the newest 1.04.18 firmware. I'm still playing with it in pre-deployment mode so it is up in my study on the main network connected to the same switch as my PC and NAS (D-Link 321). I've already noticed that Avatar.m2ts loses audio when streamed via SMB but streams perfectly when streamed via DLNA (already a big plus over my Seagate FAT+ which chokes either way). I have Dark Knight.m2ts and some other VC-1 titles, so I'll load it to the NAS and give it a try in the next day or two and see what the limits are on my system. I'll primarily be going after the highest bitrate rips (i.e. StarTrek 2009 = 39.8Mbps) regardless of codec to see the limits, but I'll make sure I throw a couple VC-1 titles in there also to see if I duplicate your observation.

For those running bit-rate tests, you may find these CBR test clips to be of use:

Thank you.

Just for fun, I will try Avatar via SMB/CIFS and see if I get any stutter. The avatar m2ts file I have on HDD now is untouched, a 1:1 copy. Separately, I need to re-mux that thing, and see if I can fix a sub-title problem.

That is very interesting. I might try those test files out. Thank you for pointing that out. I also realized that I can use Google Docs to host that Excel file I spoke of earlier (duh).

To give you a data point, I have a full-rate VC-1 encoded m2ts rip of Dark Knight (I don't recall whether I used DVDfab or MakeMKV to rip it).

I was having many of the problems other folks were reporting @WDC forums with FW versions beginning with 1.03.49B for Live+. So I'm now using 1.0.39B (which was a beta) or 1.029B (which was a production version). I've forgotten which of those two versions I'm using (what horrible revision control in my home!) but its definitely not 1.03.49B, 1.04.10B, or 1.04.18B.

Anyways, my Dark Knight rip is running OK using CIFS/SMB over my home LAN. Works either with a single drive on a PC or off a RAID-10 server. I don't recall if I tried any of the latter buggy FW versions to stream Dark Knight .... so if you have the time, you could try reverting to 1.03.29B or 1.03.39B and seeing if the VC-1 issue goes away. It might also be worth checking in at the WDC forums to see if anyone has reported a similar issue.

In my system it happens early. Right after the scene where he wakes up from cryo, when the shuttle takes off from the mother ship I lose audio when it hits the atmosphere and the audio stutters all through the landing. When I switched to DLNA it played perfectly.

Thank you for your reply. You might have missed my point…? I can also stream the 1:1 copy of The Dark Knight without any problems at all… but only if via Network Shares SMB/CIFS (method #1 only).

The problem I am dealing with, and asking other Live users is; Can you do the same (or any other VC-1 m2ts) if using Media Servers UPnP/DLNA (method #2)…?

I have not used DVDfab or MakeMKV. I am only using AnyDVD to copy the files off disc and play it using the Live+. I try not to do ANYTHING because I am lazy and/or have little time to deal with tweeks. I just want my DVD/BD’s on my media player. I have only used Tsmuxer to fix non-seemless branching or to down-grade some HD-audio, (not that I want to) and this only sometimes.

Please playback your m2ts VC-1 movies via Media Players (aka UPnP/DLNA, aka Method #2) and let us know what happens. As stated before, the same VC-1 files playback OK if the file is on a USB drive connected to the Live. I am just having a problem with BR duplicates of VC-1 if playback is via Media Players; UPnP/DLNA.

UPDATE: playback problem of VC-1 encoded m2ts files via WDTV Live+ DLNA is not associated to the Live (thanks for your assistance Kelson, Hydrogin and sinker442).

Sorry, I missed the part where you said Method #2 was using DLNA/uPNP. I don't use a uPNP server but I've heard that's a better route for network performance (everything else being equal) than CIFS/SMB - at least according to Synology (some tests they ran using their NAS boxes).

If you can tell me how to get MS Media Player to run in a uPnP server mode, I can give it a try for you. I'm running Win7.
post #6402 of 7090
Here is a picture (almost shows it all) of the Excel file that shows testing results of m2ts file playback on my Live+ v1.03.49, while using other media players and media servers. The picture lost some color to reduce the file size for posting here.

Thank you. Yeah, strange thing about the picture I uploaded and posted yesterday…. It was a BMP when I uploaded it, and now, some AVS Bot or Mod changed the file extension to JPG. Yes, I should have used PNG. For the sake of learning what happens when posting a PNG here (and for comparing results), I will now post the same image, this time uploaded as a PNG file.

For anyone just joining the broadcast, the picture can only be appreciated if you read my post from yesterday (about m2ts VC-1 playback problems via UPnP/DLNA).

UPDATE: the attached thumbnail was uploaded as a PNG file. I came back 20 minutes later, and see that the file is shown as a JPG. AVS must have a Bot that is changing this (or other formats) into JPG. Hummm? Whatever. The results are different tho, the uploaded PNG had more colors and this JPG also has those additional colors. Despite the Bot conversion thing, I see that uploading as a PNG has benefits.

FWIW Dept:
I have never used the Live (with an attached USB HDD) as a network storage device to transfer files to/from my PC. For testing purposes only, I transferred a 38.6GB file from the Live-USB HDD (in the living room) to my Ready-NAS in the office. (file was avatar.m2ts). The transfer took 2 hours and 52 minutes. I was not using my PC during this time, -so the transfer speed and process would not be affected. I knew it would be slow, but that was slower than what I was hoping for.

Test results of playing Avatar.m2ts on Live+ via Network Shares; Playback was perfect, no stutter of video or audio. Only watched the first 8 minutes tho. 8 minutes is beyond the point you described. Mite be your router or switch?

Despite my efforts to playback BR files via networking, this is primarily just a test. I want to know the limits and fix my Live and network to do the best that it can. I have given up on network streaming these BR movies (for now) but will continue testing to understand what it can and can not do. I will store my BR stuff on USB HDD (want to jump to that RAID solution soon) attached directly to the Live. This however is a problem when your collection is split on different storage devices (BR on local USB verses dvd.iso's on NAS). This "storage division" is clouding what I want next -> I need to leave the world of flat file navigation and move on to a real UI with movie cover art. On a related note, I remember a recent post here that began to address this issue, -talking about soft links. That's another post for another day.

I need to find out which movie (I have or do not have) has a very high/highest bit-rate and test drive it, because I have not found one that stutters yet; since my fix described in a post yesterday but I have only tested 5 or 6 movies so far. I have about 50 BR discs, but do not have the one you pointed out, -Star Trek 2009.

OK, I've done some tests on my network with some high bitrate BD.m2ts and I must say I am impressed with the performance of the Live+.

Configuration:
  • WD Live+ FW = 1.04.18
  • NAS = D-Link 321, 4TB, configured for SMB & DLNA
  • Live+ and NAS hard-wire connected to same 10/100 switch
  • No other network activity while the streaming tests were being done.
Source:
  • Main_title.m2ts rips from the original disk using DVD Fab.
  • Ripped the main title to BDMV structure then pulled out the .m2ts file from the BDMV\\STREAM folder.
  • Each .m2ts file contains only three streams: the main title, the English HD audio stream and one English subtitle stream.
  • Overall_bitrate/max_bitrate was obtained using Mediainfo.
Title Overall/Max Bitrate Encoding
StarTrek 2009 39.8/48 AVC
Transformers II 39.7/48 AVC
Transformers I 38.6/48 AVC
Avatar 34.8/48 AVC
Dark Knight 28.3/48 VC-1
These are the highest bitrate titles I have. For the test I played the first 10 min of each title. With my Seagate FAT+ they would stutter almost immediately and/or lose audio.

Streaming from SMB shares:
This was a little tricky. The first time I played Dark Knight it stuttered right from the opening credits and continuously stuttered for the first 10 min. The second time and subsequent times I played it, it played perfectly. Startrek and Transformers I & II played nearly perfectly for 10 min. During the first 10 min I saw 1 or 2 instances of a very slight and brief stutter. When I did a FF, I would see a greater degree of stutter upon resume-play, as if the stream got "knocked off the track". Like Dark Knight, the second time I played the titles they were perfect including playback after FF. The only title that would reproducibly stutter at the same scene each time was Avatar.

Overall, I was surprised and very pleased with the network BD.m2ts performance of the Live+. I seems it could have have a little trouble with the "synch" upon starting playback and if so you could see some stutter, but restarting the title resulted in perfect playback. Frankly, I'm impressed.

Streaming from DLNA Media Server
This is easier to report on. Every title streamed perfectly -- first time and every time including after FF operations. Not a hint of a stutter anywhere.

Sorry Marde, that includes the VC-1 Dark Knight. I can't reproduce your problems. I streamed it between streaming the other titles and so gave it multiple shots -- each time it streamed perfectly via DLNA.

Awesome work. Thank you so much. I was surprised with the DLNA VC-1 thing, but also happy that I finally know (with 2 reports) that my issue is my issue and not something universal. I am guessing that my issue may be coming from my (old) Ready-NAS NV+. (-and that my testing effort to use another DLNA server may be associated to the combo of my PC and TVMOBili.) I will work on further troubleshooting, and post back with my results when I have something to report. Thanks again.

That is pretty slow, but not surprising. You put your PC as the middleman for the transfer. Your PC has to suck the file out of the Live+, spool it on your PC HDD then send it back out on to the same network line to your NAS. Full duplex does not mean you get full network speed coming and going to two different destinations.

Try initiating the transfer from the Live+. Use the file management utility in the settings menu to push the local file direct to the NAS (or pull it down directly from the NAS). No middleman and the PC doesn't even have to be on. It will be quite a bit faster.

That is the configuration I have been using with my Seagate FAT+ and will continue to use when I replace it with the Live+. BD.m2ts on local storage and DVD.iso and TiVo HD.mpg on the NAS. Despite my findings that I can probably stream all my BD.m2ts over the network via DLNA, my entertainment center is connected to my main network via powerline adapters. It will be interesting to see if their ~50Mbps throughput is enough to support BD streaming on the Live+ -- but I doubt it. I don't mind the segregation because the demarcation is pretty clear. I am list oriented and the Live+ interface makes it easy to navigate the folder structures everything is organized in.

IIRC you are not using a 1.04 series firmware. Try upgrading your Live+ to the 1.04.18 firmware I've been using and see how that impacts your VC-1 problem.
post #6411 of 7090
@Kelson

About powerline adapters: I no longer use them, but about 2 or 3 years ago I did. When I first tried to stream BR stuff, there was too much stutter. I bought a different & new powerline adapter set Netgear XAV101, and got BR to stream OK, but had some stutter on some movies. This was using Tvix 4000 and 6500 media players via SMB/CIFS -and- the same NAS & router that I use today. The Tvix players can not do UPnP/DLNA. Flash forward to today; I am not using the Tvix players anymore, but still have them in use at other locations. A couple days ago I updated my router firmware and since then, no longer have BR stutter. My suspicion is that the stutter I experienced 3 years ago (with the Netgear XAV101) was not coming from the powerline adapters, but from my router (that was just fixed with new firmware). I could setup my current system with the powerline adapters and test it, but am too busy/lazy to do it any time soon. You might have some good luck streaming BR movies via your powerline adapters, dependant on the quality/performance of them. Good luck.

New Live+ firmware: Yes I will try it soon, but do not think my VC-1 issue is related to Live+ 1.03.49. I need to hit the ReadyNAS forums and see if there are reports of my issue there. Man, I sure wish I had a new/different NAS I could use, and then easily see if the issue is caused my current NAS.

Slow file transfer speed from Live to PC to NAS. Yes I think your right. Will do some tests within a week and post back. No real concern for me, because I will never do that again. But will want to do PC -to- Live USB HDD transfers, which should be faster than the Live-to-PC-to-NAS thing.

Thanks again for your help, time & testing

No time to work this now, but I think I just stumbled into the beginning of the end.

A post at the ReadyNAS forums (from Jan 2010);

A Reply at that thread;
It seems as though all the failing files have one thing in common, according to your log: VC1 stream
^^ This is/was a ReadyNAS NV+ issue with VC-1. ^^

Will not have time to work on this until Sunday or next week. Really looks like my issue has been the Ready-NAS.

UPDATE: playback problem of VC-1 encoded m2ts files via WDTV Live+ DLNA is not associated to the Live (thanks for your assistance Kelson, Hydrogin and sinker442). The problem has been isolated to the firmware of the NAS I am using. The problem has been fixed with a new firmware just released (Feb 2011). The firmware is ReadyNAS NV+ ReadyDLNA version 1.0.19. There is also a fix (using upcoming/new firmware version 4.2.16) for newer ReadyNAS devices such as the ReadyNAS Ultra-6+.

^^Congratulations. Although the fix may not be within ready grasp, knowing the cause is half the battle and most satisfying. At least now you know what to complain about. Good luck.

Well, this was an incredible surprise. I installed my Live+ into my entertainment center rack (pulling out the Seagate FAT+) and repeated the high bitrate BD.m2ts streaming tests I reported on above. Only this time the connection back to the NAS is through 2 switches and a pair of powerline adapters. Bottom line -- high bitrate BD.m2ts stream perfectly. Now I am really impressed with the performance of the Live+; and more than a little happy with the PLA's.

Configuration:
  • WD Live+ FW = 1.04.18
  • NAS = D-Link 321, 4TB, configured for SMB shares & DLNA media server
  • AV link:
    Live+ HDMI into Onkyo AVR
    Onkyo HDMI into Panasonic plasma
  • Network link:
    Live+ connected to Netgear 5-port 10/100 switch
    Netgear 5-port connected to one end of a pair of Netgear AV-200 PLA's
    other end of PLA pair connected to Netgear 8-port 10/100 switch
    D-Link NAS connected to Netgear 8-port
  • Throughput across PLA's = ~50Mbps (measured by timed file transfer)
Source:
  • Main_title.m2ts rips from the original disk using DVD Fab.
  • Ripped the main title to BDMV structure then pulled out the .m2ts file from the BDMV\\STREAM folder.
  • Each .m2ts file contains only three streams: the main title, the English HD audio stream and one English subtitle stream.
  • Overall_bitrate/max_bitrate was obtained using Mediainfo.
Title Overall/Max Bitrate Encoding
StarTrek 2009 39.8/48 AVC
Transformers II 39.7/48 AVC
Transformers I 38.6/48 AVC
Avatar 34.8/48 AVC
Dark Knight 28.3/48 VC-1
These are the highest bitrate titles I have. For the test I was going to play the first 10 min of each title, but was so impressed that I ended up watching about 30 min of each.

Streaming from SMB shares:
Forget it. Looked like 2-3fps and no audio right from the start.

Streaming from DLNA Media Server
Incredible. Every title streamed perfectly through the powerline adapters -- including after FF or RW operations which were not real smooth but very acceptable. Not a hint of a stutter anywhere. The Live+ bitstreamed the DD TrueHD tracks from Dark Knight, Transformers I and StarTrek 2009. First time I've ever heard HD audio -- not bad.

Bottom Line:
The main conclusion of this post is really about powerline adapters. Many people have asked in many threads whether or not PLA's can be used to stream BD. So here I present a specific case in which I can say that if you can get ~50Mbps across them and have a server capable of DLNA/UPnP then you are absolutely good to go with a WD Live+ and high bitrate BD.m2ts.

Your analyses of direct and powerline performance were detailed and informative. Thank you.

I'm considering powerline adapters. Were yours in close physical proximity? On the same power circuit?

Yeah I agree, fantastic job Kelson.

Also see his associated report at this thread that discusses PLA's. http://www.avsforum.com/avs-vb/showthread.php?t=1312088

They are on different circuits. My main network is upstairs centered in my study. The entertainment center rack is downstairs on the other side of the house. What is not clear to me is whether or not the two circuits are on the same phase line or cross the phase boundary in the box. The electricians never properly labeled the circuit breakers in the box.

Kelson, interesting work. One question on powerline equipment, how are different circuits on the opposite side of the circuit panel handled? I've been using X10 stuff for well over a decade, and without a coupler any circuits on the other side of the feed will not get a signal, is this true to with powerline networking?

According to the specs. of the AV-200's they are supposed to handle communication across the phases, albeit with some hit in bandwidth. As I noted above, I'm not sure if the two circuits I have them on are on the same or opposite sides of the box.

Has the a/v sync issue been fixed with this yet? I used this last about 7 months ago and all my movies would eventually drift out of sync (mostly .mkv but some .mp4 and straight .mpg dvd rips). This was especially obvious if a movie had been paused for a day or 2 (don't ask). what is the considered the best firmware for connected drives and a/v sync reliability? i.e. not interested in networking etc.
