A2/XA2 firmware upgrade 1.2/1.3 [ remove disc first!] - Page 34  

post #991 of 1198
To repeat what I said, I agree that there should other means besides the Ethernet connection to permit updating the firmware.

This is probably why Toshiba sends out the firmware discs to those who request it.
Average joe doesn't even have to own a computer.
Call em up and ask for a disc!

Hi, I have a question
I have a hd dvd hd-a2 and a receiver yamaha rx-v1700, i conect it with hdmi and optical, when I select the sounds (DD+ and DDtrueHD) with optical output, the receiver show me a dts audio and when I use a hdmi conection the receiver show me pcm audio
who its better or I need configurate more details in my receivers?
thanks
post #993 of 1198
alpeg, I have exactly the same set up as yours. I'm also using the Tosh HD-A2 & Yammy RX-V1700.

Yes, if you're using optical output the audio will be down mix to DTS (at a 1536 kbps) while using HDMI the player will decode & output PCM signal to the receiver.

TrueHD is definitely better than D+. In fact, TrueHD (lossless & supports up to 18 Mbps bit rate) is better than DTS 1.536 Mbps. However, when I tested some scenes from Superman Returns using a sound level meter, TrueHD achieved slighly higher 1 or 2 dB than the DTS while in other scenes both of the audio formats achieved similar results.

Hence, the question is how do we verify that our receiver is receiving/processing/playing the correct audio sampling frequency & bit rate (TrueHD output as PCM tru HDMI).

Using physical hearing, it's hard to really differentiate the two (probably due to my low-end HT equip). Nevertheless, I feel TrueHD gives a slightly better punch & its surround is also crispier than in DTS. Just my 2 cent observation.

Over the past few weeks I've asked this same question on various threads including this one and have not received any answers. I'm beginning to think there is no data in the Signal Info or related info that can tell us definitively this.

I think the closest we have is to verify that HDMI output is set to AUTO and that the receiver shows it is getting MPCM. Some say to also set the SPDIF setting to Bitstream but I do not know if this is mandatory. Rather I think it was used to get past a bug with screeching which may have been fixed with the 1.3 firmware update to the A2/XA2 anyway. Not sure.
post #995 of 1198
Yes, lovingdvd was the first person who highlight the issue but sadly until today it's unresolved.

I set my SPDIF setting to Bitstream but my receiver will auto detect the audio signal with priority given to HDMI. My other concern now is my RX-V1700 receiver is also unable to show the audio sampling frequency in 96 kHz in which others members claimed when using a different receiver.

*lovingdvd, have you tried writing in to Yamaha customer support (inquiries) to get their feedback? I just sent my comments to them using the global form. Perhaps you can give it a try using the USA site. Let's wait & see how eficient their response.

Most consumers have more than one TV, and usually the typical consumer will gradually replace their TVs and associated equipment. So once the primary TV is replaced with an HDTV with DVI or HDMI, now it makes sense to purchase an inexpensive upconverting DVD player (or a reasonally priced high definition player with upconversion capabilities). Once this decision is made, there is less of a burning need to start a completely new collection, and the investment in standard DVDs is preserved for many years. Not everyone has a large display. For smaller HDTVs the consumer may not see much of a difference between upconverted standard DVDs and high definition discs. For them it may make more sense to continue to purchase most of their discs in the less expensive standard format, converting it to near-HD quality.

Hi Larry,

Once again I agree with you but, I also own the HELIOS H4000 HD Upscaling DVD Player and it does upscale standard DVD's up to 1080p through component inputs. Here is a little description if you are not already familiar with this player-

"The sleekest 1080p upscaling DVD player that's guaranteed to bring edge to your home theater.

The HELIOS H4000 HD Upscaling DVD Player is possibly the only player in the market that can bring your home theater images to a stunning 1080p HD resolution through HDMI and component outputs, and what more, through VGA/RGB-HV outputs as well.

With 10 different resolutions to choose from, the H4000 upscales not only your standard DVD titles, but also "home-made" DVDs, not to mention MPEG4 formats such as DivX and XviD stored in your CDRs and DVDRs. Its VGA/RGB-HV outputs even give you the ability to upscale to 1080p on your projectors. And with 576i video output via HDMI, the H4000 is ideal for your external video scalers.

Features

* Playback format options:
* DVD/SVCD/VCD/CD/HDCD/MP3/MP3/WMA
* MPEG4(DivX, Xvid, MPEG1, MPEG2 and MPEG4) video file file playback.
* 1080p support via HDMI and Component.
* Hi-Def output options via Component interface in 720p,1080i and 1080p
* Hi-Def output options via VGA/RGB-HV interface is 640x480,800x600,1024x768, 1280x1024, 480P,720P and 1080i.
* Hi-Def output options via DVI(via HDMI to DVI cable) interfaces.
* 576i video output via HDMI for external video scalers.
* NTSC 720P/1080i/1080p support at 60hz
* PAL 720P/1080i/1080p support at 50hz"

It truly does live up to their claims. I played three standard DVD movies upscaling to 1080i with this Unit and then played the same three Titles in HD DVD format on the A2 and I had a pretty hard time telling the difference. I have the following three movies in both formats - Mission Impossible, We Were Soldiers and King Kong. I used my wife for an unbiased opinion. She is not into "Hi Tech Gear" but as an Interior Decorator she has a good eye for a clean, sharp and vibrant picture. I played the same scene for each movie on both players and she picked the HELIOS twice for better picture quality - Mission Impossible and We Were Soldiers. She picked the HD-A2 when I played King Kong. I am not in any way promoting the HELIOS or at the same time taking anything away from the A2, I just think that there are still very affordable alternatives ( I paid $149 ) for people that still have analog HDTV's and a large library of Standard DVD's. Bottom line, I am all for HD DVD and hope Toshiba doesn't back down with the format war with Blu-Ray!

Ron,

I'm curious about what you just described. I believe you by the way. Which cable did you use to upconvert the SD DVD images? You were either comparing HDMI or DVI on the Toshiba to either HDMI/DVI/Component or VGA on the Helios. I assume you used HDMI with both players but just would like a confirmation.

You're making me think I should dump my Oppo 971 for this Helios player. What is your opinion on that? I have the RCA HDV5000 HD DVD (re-badged HD-A1) player.

Thanks Ron!

What is interesting is that for such a hot topic (TrueHD, DD+) there seems to be no experts in the audio, receivers, or HD DVD threads able to offer any definitive advice on the matter. Mostly its other people reiterating what others have said, and others just asking the same questions. I find this a bit bizarre since I would think among us are at least a few gurus who know what the deail is.

Basically here is my current line of thinking on this... First people say to set Bitstream for SPDIF even when using HDMI. I found that in some cases when I had SPDIF set to PCM I would get some screeching or weird sounding audio (obvious problem, like someone talking through a kazoo) when I listed over HDMI. Setting SPDIF to Bitstream I never had this issue.

So for one I'm thinking the advise to set SPDIF to Bitstream is more about working around that issue than one of being able to get TrueHD. IIRC there are notes somewhere that the 1.3 firmware for the HD players addresses screeching and if that's the same thing I think they are referring to this may have resolved that bug. I haven't checked that yet.

Next, I find it interesting that they have the default for the XA2 set to PCM for SPDIF. I would think that if getting TrueHD did require SPDIF set to Bitstream even when using HDMI that they would not default it to that.

The other thing I'm confused about, which I reported a few weeks ago, is that when SPDIF is set to Bitstream I get 96khz to the receiver. When I switch it to PCM I only get 48khz. So we have people telling us to set SPDIF to Bitstream to get TrueHD, and yet this results in a lower 48khz vs. 96 rate. So TrueHD is only supposed to be 48khz? Some people have told me yes, that its a bandwidth thing. But it doesn't seem to make much sense.

I would say this however - when I switch between DD+ and TrueHD on the POTO HD DVD, for instance, I *definitely* hear a noticeable improvement in TrueHD. It certainly is a bit louder in TrueHD, so one has to be careful not to just think it sounds better because it is louder. However, it does also seem a bit crisper and wider this way too. So although I do not see any difference in the Signal Info reported by my receiver when I switch between DD+ and TrueHD, I do hear an improvement.

I think tonight I'll go back to setting SPDIF to PCM and trying this experiment switching back and forth between DD+ and TrueHD. If I still hear the improvement going from DD+ to TrueHD, I may leave it in the PCM setting if indeed it shows 96khz instead of 48khz, and if there is no screeching.

Well I've given up calling their technical support in the USA. They actually have tech support people that answer calls (as opposed to just customer service type people like if you call Toshiba tech support). Although the Yamaha techs I've spoken to seem knowledgeable about the products, they have repeatedly given me wrong answers on a variety of topics. I did ask a question using their global web site form (unrelated to this) - its been over a week since I did that and I haven't gotten any response. So unfortunately, no, it doesn't seem like an efficient vehicle to reach them.

Tnx lovingdvd for the sharing. I almost gave up after trying so many futile attempts but after reading your feedback & based on your suggestion, I tried one last time..and guess what....it works! Fyi, I've upgraded my Toshiba HD-A2 to the latest firmware 1.3 (I'm not sure if this is relevant to my test).

Now the only thing I did was setting my SPDIF to PCM & HDMI to AUTO. (both the SPDIF & HDMI are connected to my Yamaha RX-V1700). Then I poped in the Superman Returns which has the TrueHD option, then did a quick check on my AV receiver SIGNAL INFO...voila...! The sampling rate shows 96 kHz! Then I used another movie, Poseidon & confirmed the result.

There's no screeching or weird sounding audio, etc. Everything sounds perfectly normal. So far, my findings reveal the following:

1. Both D+ & TrueHD result in 96 kHz sampling rate.
2. For TrueHD, I selected the Optical audio playback, but it only has 2 channels & with sampling 48 kHz.
3. Using the same setup, I also tried two different DTS 96/24 demo discs, all output at 1536 kbps but with 48 kHz only. I'm not sure if this is accurate. I'm doubtful both materials are inferior in quality (will try other discs too) ...

Tomorrow, I will try to compare btw TrueHD (tru HDMI) & DTS (tru Optical) to observe any audible difference.

Hi, Ron,
Thanks for the info on the Helios. You really got me curious, so I've just ordered one. I will enjoy comparing it's SD DVD upconverting abilibity with my A1 and XA2.
post #1002 of 1198
Around a year ago I ordered the Helios Player based on positive reviews. However, I had the opposite impact. the upscaling was very bad and was easily the worst DVD player I have ever owned. I would look and see if there is a secrets review on this player. At the time I had a Panny 7 series 50 inch plasma. I replaced the Helios with a Denon (I think it was 1920) to the Oppo 971 until I got the XA1. I then used my XA1 exclusively for all DVD and HD DVD. I now use the XA2. Both the Denon and Oppo were good solutions but not the Helios. I even got a couple of the Hi Def disks that were playable on the Helios Player....

Just providing my data point. The Helios upconverting will not make your SD look close to HD. This is just flat out wrong.

My 2 cents.....

EDIT: I ordered the Helios last year around Feb.

Hi Wayne,

I was using Component cable to upconvert the SD DVD's. This is a rare and very impressive feature of the Helios H4000 player. I was also using Component cable with the HD-A2. So we are comparing "apples with apples". I do not believe the Oppo 971 can upconvert through component, just through HDMI/ DVI. My main goal for the post was to give those of us with Analog HDTV's , without HDMI/ DVI inputs, an alternative for greatly improving their already established SD DVD Collection to near HD quality using Component inputs. If you're monitor has HDMI, which it sounds like it does, than the HD-A2 is the way to go. If you're monitor/ display doesn't have HDMI/ DVI than I would recommend the Helios H4000 over the Oppo 971 for upconverting.
I just want to make myself clear, I am a big fan and supporter of HD DVD and I am not in any way trying to promote the Helios as a replacement for HD DVD players. I am one of the millions out there that has an analog HDTV, without HDMI, so the Helios for upconverting and the HD-A2 for HD DVD makes a great Team for me.

Ron

Did anyone ever get the internet update working after receiving the "already updated" message (without using an update CD)? I have an October 2006 HD-A2KU made in China with 1.0 firmware. The humorous part is I waited this long to buy one so that I would get a fresh build with 1.2 firmware! I hope they are all the same hardware wise. I've downloaded the ISO for 1.2, but my other computer is down right now and it has the burner.
post #1005 of 1198
On our new A2 I see these numbers/letters in the Maintenance/Update area....1000/T17T. Does anybody know what this means?

Thanks.

It means you have the original version of the firmware. The current version is 1.3.

If you wish to update your firmware to 1.3, the only way to do that at the moment is through an internet connection, as described in the owner's manual.

If you get the "your firmware is already updated" message, then you will need to update the firmware to version 1.2 first, either with a disk supplied by Toshiba or creating your own using images posted on the internet. There are several links mentioned in this forum.

Thanks Bob! I just did the online registration for our A2....will Toshiba send out the newest firmware disc automatically...or should I call Customer Service on Monday and request it??

Toshiba should send out the disk "automatically", but a phone call never hurts. This assumes you indicated somewhere in the registration that you wanted firmware update disks sent to you. When I registered my A2 by mail, that was "kind of" a choice.

By the way, the disks for the 1.2 update have only gone out recently. I'm not sure when the disks for the 1.3 update will be mailed, but based on the experience with the 1.2 update, it could be several weeks from now.

I gather that you do not have an internet connection close to your player. If you do, that might be a faster way to get the firmware update.
post #1009 of 1198
Bob,

Our internet connection is kind of confusing...we are using a wireless connection to our current computer....through the tower on our old computer. So, we often have interrupted service...only a few seconds at a time. I'm not sure if that would be a problem....but I don't think it would be worth risking it.

So far, through the 2 hd dvds we've played so far....we haven't had a problem yet. So, I don't know that the firmware is desperately needed right now in our situation. We use HDMI to HDMI in our connection. I know there are other issues that the firmware addresses, but as for now....I am willing to wait a few weeks for the disc to arrive (really don't have a choice).

I appreciate all the help, Bob!

I still remain completely mystified as to why changing the SPDIF setting between PCM vs. Bitstream affects the sample rate received over HDMI (96khz vs 48khz respectively)!!
post #1011 of 1198
I was eventually able to update the firmware on my A2 to 1.3 thru ethernet.

Unfortunately, I still have the same problem going thru HDMI/DVI to my Sanyo Z2: I can get 1080i on either HD or upconverting SD only for about 2 minutes. Then the projector loses sync and I get a blue screen from then on.
post #1012 of 1198
I just updated my HD-XA2 to firmware version 1.3. Updated was completed via ethernet connection to my route in approximately 30 minutes. Absolutely no problems. I did not initialize the player after the update. Everything appears to function as expected. Unfortunately, the internal subwoofer test tone still does not play and the subwoofer is basically non-existent from a test disc such as Avia (without serious fidling of the levels of course). All told, the upgrade was painless. I sure wish they could get this subwoofer issue worked out though.
post #1013 of 1198
I just updated to 1.3 and I see the HDMI handshake issues are completely gone. You can change input and even turn off the tv and the player will stay in pause (if you paused it) or continue to play on. It's nice to not worry about this anymore.

Unfortunately the low volume levels persist, so I hope the next update will target this.

Hi Ron,

Thanks very much for the information. Needless to say I erroneously believed that copy protection issues prevented upscaling on component video.

I've got an old first generation HDTV that has RGBHV high definition inputs. The HELIOS player looks like its the only player that would permit me to upscale DVDs without having to buy a transcoder to convert from component video to RGBHV. I believe that most decent transcoders cost twice as much as this player.

Hi,

Thanks for the candid response.

Could you please elaborate on your experience playing high definition discs? What type of HD discs were playable on the Helios? Was HD playback a "hit or miss" thing or fairly reliable? What was the quality of playback of HD discs?

You mentioned that the upconverting of standard definition DVDs didn't look close to HD, but did the player improve the apparent resolution of DVDs, that is, did it make DVDs look better?

Thanks.

Yes, I can confirm that my receiver displays both DD+ & TrueHD in 96 kHz sampling rate. Previously, my receiver only showed 48 kHz but after changing my audio setting in SPDIF to PCM, the problem is corrected. I didn't ralized the SPDIF setting was the culprit.

I wanted to try TrueHD over Optical, so I selected the audio output to Optical in my receiver (I have both the Optical & HDMI cable readily connected). My setting remains the same: SPDIF is set to PCM.

The result: My receiver detects the signal in PCM but only 2 channels. There's no 5.1 as per my expectation. The SQ when using Optical sounds totally "unpleasant" & way off as compared to TrueHD.

However, if I change my SPDIF setting to BITSTREAM, then using the Optical output will result in the DD+ & TrueHD downmixed to DTS at 1536 kbps with a sampling rate 48 kHz. My receiver also display such info correctly. This mode sounds much much better than using the PCM setting.

I still remain completely mystified as to why changing the SPDIF setting between PCM vs. Bitstream affects the sample rate received over HDMI (96khz vs 48khz respectively)!!

I have both cables on standby as I was carrying out various tests & regularly switching back & forth btw the two to compare the audio quality, etc.

So, my final permanent audio setting is: SPDIF --> PCM while HDMI --> AUTO

Yes, me too am also puzzled why changing the SPDIF setting between PCM vs. Bitstream affects the sample rate received over HDMI. Later I will try some test again, probably I will disconnect my Optical cable & will find out if the sampling rate is still the same. Hope you could do some tests & would like to hear your fedback. Tnx

Hi,

Yes, this behavior was reported in the other Toshiba players.

Here's some threads on audio issues and player upsampling.

Be sure to read KMO's response to my question in posting #6. As you can see its pretty much been confirmed that the players are upsampling the content from 48kHz to 96kHz, by this quirky and unintuitive interaction between the SPDIF and HDMI settings. However, the question remains whether this is a feature or a bug.

I just did some experiments and can also confirm that I'm seeing the same thing you guys are reporting. With SPDIF set to PCM it outputs 96khz sample rate, 48khz when set to Bitstream. Likewise the "Display" button on the XA2 remote shows TrueHD with "Digital PCM" when SPDIF is set to PCM and "Digital Bistream" when SPDIF is set to Bitstream. In both cases it also shows it is output "TrueHD".

What is also confusing is that Bitstream, the way I understand it, is basically raw data that the receiver must then decode. We all know that no receivers today can decode TrueHD until HDMI 1.3.

So further then it makes no sense that the receiver could translate the bitstream into TrueHD. Therefore I'd think one must use PCM in order to get TrueHD.

This is all very confusing, and unfortunately there does not seem to be any mega-guru participating that can provide any definitive answers. In the Video threads its nice because there are big industry heavy hitters that step in and put us in our place and clarify confusing issues from time to time. So far all I've come across is several members all similarly confused and wondering the same thing. Hopefully someone out there will have some definitive information.

So in the meantime I am settling on setting SPDIF to PCM (and NOT Bitstream which has been recommended for some reason over and over in the forums) and HDMI to Auto.

I will do some more listening between SPDIF set to PCM vs. Bitstream with TrueHD to see if one is obviously better than the other. The challenge with trying to A/B these however is that you have to STOP the movie, enter the setup menu and make the change, and then go back to where you were. In the time this takes its easy to lose your frame of reference. Too bad there is no way to toggle the PCM vs. Bitstream setting like one can do in a movie between DD+ and TrueHD.

Tnx Larry for the links So it's actually the players are upsampling the content from 48kHz to 96kHz. All the while I thought it supposed to be at 96 kHz & I was so happy when my receiver info finally display this higher sampling rate...but now it seems I'm back to square one

Hmm... when your SPDIF set to PCM it outputs 48khz sample rate, 96khz when set to Bitstream...is this done using the HDMI cable to the receiver? How strange, my result indicate the opposite of your findings?? Your HD-XA2 setting should be similar to my HD-A2 but it reveals totally different results...

Guess no harm if I will just leave the SPDIF setting to PCM and HDMI to Auto in order for the receiver to read 96 kHz sampling rate for TrueHD playback .

Geez...it's indeed very confusing & frustrating
