The big difference in this scenario is that I use an older 1212 PVR to capture.. Is the non-switching of audio a bug in the PVR 2 ?

The quick way I check for 2.0 vs 5.1 is File Properties/details in Windows Explorer, this is with Windows 7 which I am not totally comfortable with. It will say either 2 or 6 channels.
I haven't found where Windows Media Player displays the audio format. Right now, the only way I can play files on my TV/AVR is to copy them to a Flash Drive or Portable Hard Drive and play on my WDTV, which has an optical output and seems to process DD 5.1 to the AVR.

I think looking at properties & some apps like mediainfo will look at the opening frame and tell you what the audio is..
But using VLC media player will tell you when it switches..
To see if it switches back & forth. go to 'tools' & 'codec info' (in VLC)
Leave that window open as the video plays.. It will switch back & forth between stereo & 5.1 if both exist in clip..

VLC is free and plays almost every file type..

I have an older version of VLC on my desktop computer. I have a new laptop that I'm using for the PVR-2.

I tried out the stand-alone capture program from Hauppauge. It still needs some work. I tried the editor and snipped a few seconds off of the start of one of the files. The program creates a new file with a "-A" attached to the name. Now, the new file doesn't seem right, maybe the program doesn't properly close the file. The file properties don't show as they do on the original, and although the file plays on my WDTV, it's only 2 channel stereo, where the original has 5.1 after the intro.

Yeah I never use TME to edit any more. I use Video Redo.
If you don't want to pay $100 for VRD you can use Tsmuxer to trim or cut h.264 files. It's free.
You can't visually edit the file with tsmuxer but you can tell it to trim the video by a certain amount of time..
It's also a great remuxing tool. It can author BD's, AVCHD's & remux MKVs.

Yeah, I am probably going to get VideoRedo. I have Tsmuxer but haven't tried trimming yet.

I have tried making a BD and AVCHD, but they wouldn't play on my player.
post #36 of 240
nikknight, I have been busy and had a few programs to record using the PVR-2, so I haven't had the time to experiment.
I tried trimming a video with tsMuxer, and it produced a file, except it was in 2 ch where the original was in DD 5.1. I can't find any settings that might make a difference, but does it work correctly for you? Am I not following the correct procedure? I check the "enable cutting" and set the start and end times the hit "Start Muxing". Do I need to demux first, then mux the files?

As far as Windows Media Center goes, I can only give you my own experiences. I'm using Win7 x64, but I have two Hauppauge 2250 tuners. Windows Media Center will not see the 1512 and there are no WMC drivers available. So, you're stuck with WinTV7. YMMV, but I've not been able to get WinTV7 to install properly and co-exist with WMC. WinTV7 starts with a ton of errors. "Failed to attach TS slip filter" and "Failed to attach TS File Reader" errors to be specific. It will eventually start and run, but it's buggy as hell. Took a registry hack to get the IR blaster to work. If WinTV and Windows Media Center have scheduled recordings that overlap, WinTV7 fails.

If you have any other Hauppauge devices installed, it will wreck the 1512's installation. The install program assumes the 1512 is the only thing you have. Customer support confirms they never counted on someone having this box AND a tuner card.

One bug that seems to be an issue for everyone is recording via component video with optical audio. There are beta drivers that'll fix that for most, but it's still gonna take some work.

All that said, I still have the 1512. In addition to WInTV7, the box comes with an old Arcsoft capture program. That's what I've been using the most.

If all you're gonna do is manually capture stuff, you'll be fine. Otherwise, get the 1212 or wait until the 1512 is ready for prime time.

The PS3 is the exception with the HDMI output; the HDCP on that is enabled at all times so you're forced to use component to capture anything from the PS3. The Xbox 360 and other consoles doesn't have that problem.

Sorry, I'm subscribed to this topic but never received any notice that there were new comments ..
tsmuxer shouldnt change the audio to 2.0.

Are you still using the windows properties tab to look at the audio?
Did you try using vlc to monitor the audio.

When you load the file into tsmuxer does it say the audio is 5.1?
Is the first frame of the edited file 2.0? Is it a commercial or something?
Your process seems right. Just load the file, choose the format for muxing, enable cutting and adjust the time to cut.
then 'start muxing'.

I think I originally used windows properties tab to look at the audio, it said 2 channel.

I have since installed VLC Player and just did a quick test.
VLC shows 5.1 audio, but it is out of synch when I play the file on my WDTV (or computer for that matter).

I'm hoping that VideoRedo works without these problems, I just haven't gotten around to ordering it yet.

Are you capturing mp4 files? I've heard they have sync issues when captured with the Hauppauge units..
I'm not even sure if tsmuxer accepts mp4 files so this question might be moot.
post #41 of 240
No, I'm capturing .ts files, they seem to be the best choice right now.

The audio is out of synch if I move the slider maybe 15 minutes into an hour program. It seems in synch if I move it around the 50 minute mark.
If I start it at the beginning and let it play, I think it stays in synch. This is using VLC or Windows Media player.

There's not enough time in the day to check all the possible variations.

I reported the Hauppage Capture "bug" last week (audio must be 5.1 when you press the "capture") , but haven't heard back from them.

A lot of people using the 1212 thought this was a bug also. But with the 1212 the audio switches back n forth between 2.0 & 5.1 depending on what the clip has in it..
Did you try my vlc test?
play a file that says it's 2.0 with the video codec window open. it doesn't switch from 2.0 to 5.1 ?

I will repeat the test, just to be sure, later today.

There's a Hauppauge help forum, but it's in the UK. I saw a message there stating "be sure the source has 5.1 sound when you press the "capture button"".

Do you experience audio sync issues using tsMuxer? The audio leads the video in the output file, where the original capture (.ts) file plays solid.
post #44 of 240
Based on my limited testing, I would make sure you're allowing enough time after changing channels before starting to record. If you start recording too early, the HDPVR will see no AC3 audio and automatically switch to stereo PCM capture mode which uses MPEG or AAC codec depending on settings. Once in PCM capture mode, I have not seen it automatically switch back to AC3 without restarting the recording. It will switch automatically between 2.0 AC3 and 5.1 AC3.

This is an area where the older HDPVR-1212 was superior. It had an AC3 2.0 encoder. The HDPVR2 only seems to support AAC or MPEG encoding for stereo PCM captures. It can only pass-through AC3 from the source and can't create it from non-AC3 sources like the older unit. I believe the Colossus had the same limitation.

I've never had any audio sync issues with tsmuxer but I only use it to mux files - I edit with VRD.

When I start my capture, I find the start of the program, pause it, bring up the info screen, capture for 5 seconds then press resume on my remote.
It's simple and it might solve issues of 2.0 swithing audio for some people..
It's also a good way to capture some info about the program... actors, date, stuff like that..
Here's what it looks like:

I did another test, captured the first few minutes of a Sopranos episode, which starts with 2.0 audio. I played the clip back with VLC and it shows "stereo" at the beginning and "5.1" when it switches into the intro song. Perhaps this is also a playback issue with my WDTV box, it only sees a flag at the beginning for 2.0 audio and doesn't detect the change to 5.1, although it works the other way when you start with 5.1.

My next test would be to examine the file headers to see if there is something that flags the file as 5.1 or 2.0. Maybe a little data editing will make it work correctly.

Nice, but my Motorola Cable box reverts to 2.0 when paused.
My workaround is to advance 5 min to where there is 5.1 audio, start the recording, wait for the capture screen to settle, then go back 5 minutes to the start of the program (2.0) and let it go. Someday I will edit out the stuff at the beginning. :-)

Yeah, I first noticed the switching audio while watching captured programs thru my Pioneer AVR.
The display on the front would start 2.0 then switch to 5.1.. (windows properties said the file was 2.0)
That's when I ''guessed' it was just looking at the first frame..
The good news is that it's not a bug in the software, It's just picking up what the source is putting out..

Video Redo (VRD) has a trial version available. It's a great piece of software to edit the start of your files... And it even has ad detective for cutting out commercials.
It does cost almost $100 tho... For that amount of money it should include authoring for BD & AVCHD.

There is no per-file AC3 format header. Each AC3 frame contains its own header where it can specify the format, frame size, etc. Since each AC3 frame is approximately 0.032 seconds of time, you would need to remove many of those starting frames which have the 2.0 format.

I find it hard to believe anyone would design a product which assumes the AC3 format is constant throughout the duration of playback. I don't own a WDTV to verify but other Sigma Designs players I own don't have any problems with such recordings.
post #51 of 240
I was able to reproduce the audio/video sync problem that has been reported in this thread. It happens either because the HDPVR2 is dropping AC3 audio frames or repeating some video frames. It's usually not a visible problem because most players will use the timestamps in the .ts file to compensate for the missed audio/video frames. The problem becomes most apparent if you split the file into audio/video streams or remux it with TSMuxer. The audio and video streams will now be different lengths and you will see a noticeable desync after about 30 minutes or so.

The audio seems to lose about 0.15 seconds per half hour of recording.

Someone should forward this as a bug to their tech support because my old HDPVR-1212 does not have this issue.

Edit: I was able to verify that the HDPVR2 is repeating some video frames. Audio seems fine but will be shorter and out of sync when demuxed. Tested on a 720p 60fps HDMI capture from a Tivo Premiere4 using their "Hauppauge Capture" application.

Well, this explains the audio sync issue. Thanks for your efforts. I'll forward this info to their Tech Support.
I'm still baffled by the 2.0 vs 5.1 audio problems I seem to be having.
post #53 of 240
I had a chance to download the trial version of Video Redo.

I had been recording my programs with a few seconds of 5.1 audio at the beginning in order to be able to play them on my WDTV media player. If I delete the 5.1 portion at the start and save a new file, the WDTV plays it in 2 channel stereo, no switchover to 5.1 later. If I leave a few frames of 5.1 at the start, the WDTV will play the 5.1 audio when it reaches that point. It also displays "Audio Channel 1 Digital" when I start playing the file. So, this is a property of the WDTV player.

If I run a .ts file through tsMuxer, the resultant file has audio out of sync because of the frame duplication that Wizziwig found. An edited file (Video Redo) still has audio sync problems when run through txMuxer.

I tried making Blu Ray files with tsMuxer and the .m2ts files in the STREAM folder had the audio sync problem. So, it looks like anyone making a Blu Ray disc from PVR 2 files will have an audio sync problem.

I did send Hauppauge Tech Support an e-mail about the frame duplication. That appears to be the most serious problem.

So if you record something from a laserdisc or VHS, it's going to re-encode the audio using aac or mpeg?

Yes. Any stereo source that is not already Dolby-AC3 will be converted to either MPEG or AAC - your choice in the settings. The older 1212 model supported converting such sources to AC3 (stereo) or AAC. To record AC3 (2.0 or 5.1 channel) on the 1512, you need to connect your source via HDMI or SPDIF and make sure it's sending AC3.

Well that just sucks. I guess I'm sticking with my 1212. Is this a software or hardware limitation? Any chance of getting an update on this?
post #57 of 240
My brother have a HD PVR2 1512 model, he want record via composite !
My friend have a Hauppauge USB-Live2 with composite.

Can I use a USB-Live2's cable on a 1512 and record with composite input ?
I verified, a plug and noticed have a same form, but inside this connector, a quantity of pin is not same !

I tested while device was no powered, and this plug fit on both device !

Does anyone tried this ?

I just picked up on of these, however, I've been unable to get it working in Windows 8 64bit. Has anyone succeeded to get it working under this OS? I'm working with tech support but they've unable to provide a solution yet. It does work fine if I run it under Windows 7 (32bit and 64bit) in a VM with a Windows 8 host. The same host the software can't start the device.

Yes. I received mine yesterday and installed everything last night. To my surprise, no surprises, except that WinTv 7 couldn't log in to the Internet at first to download the cable guide.

I followed the advice in an Amazon review and downloaded the current installer and WinTv package from the Hauppauge site. To install WinTv from a download, you need to first mount the installation CD that came in the box.

BTW, WinTv 7 does not offer (that I could find) an option to download a cable lineup from the Internet after the install phase. [EDIT: Yes it does: Gear button > Devices > select HD PVR 2 > click Tuner Setup.]

Glad to hear you got your set up going.

My problem turned out to be an incompatibility with Windows 8 with Media Center since I have MC installed. I sent the info to Hauppauge so hopefully they'll have a fix so their stuff can co-exist with Media Center.
