I am having problems streaming DVD format mpeg-2 files to my DMA1000 from TwonkyMedia.
Most of my files are 720x576, 25fps, PAL, AC3@48Khz, 2 channel and these all fail with an "Unsupported format" error. These fail when streamed from DiXiM also.
Interestingly, non-standard resolution work mostly
704x576, 25fps, PAL, AC3@48Khz, 2 channel, but Twonky reports an incorrect running time. The running time is reported correctly on DiXiM.
I know that this looks more like a DMA-1000 problem, but has anyone had any success with these formats (pretty standard!) or can offer suggestions as to what formats may work correctly or what may be wrong with the ones I am trying.
All of the files have been recorded from DVB-T using WinTV, if it matters.
I am running TwonkyMedia 4.4.3.1 on a LinkStation Pro
Problems streaming MPEG-2 to Zyxel DMA1000
Thought that I'd let you know that I had problems with playing one movie in particular until I upped the firmware on the DMA-1000.
The firmware is available on the zyxel.com website. Put it on a USB stick to up the firmware.
I had a little fear that the update stayed on 50% completed for many minutes, and on 99% too for a long time - I'm glad I didn't switch it off!
After upping the firmware to the latest, the movie played fine.
Hope this helps.

Problems with DMA1000 turn out to be problems with DVB-T
Thanks for the tip, I had already updated the firmware to no avail, although it did allow me to play MPEG-4 files that I had been previously unable to. I agree that the long time the firmware update takes is scary.
However, I think I have "solved" the problem. The problem is that these are DVB-T streams which have slightly strange audio encoding as documented here:
http://forums.dvbowners.com/index.php?showtopic=6844 and see also http://www.dtvforum.info/lofiversion/in ... 45736.html. Note that this is not talking about the Zyxel DMA1000 but rather the Sigmatel 8621 chipset in general. It seems they all have a problem decoding these streams (although software based players seem to work perfectly fine). I have tried re-outputing the stream using VideoReDo (http://www.videoredo.com/en/index.htm) and this does indeed fix the stream so that it will play on the DMA1000. VideoReDo is also nice because it is really fast - only taking about 3 minutes to fix a 4Gb movie.
Since this is a problem/limitation with the 8621 chipset it seems unlikely to me that Zyxel can fix this with a firmware patch. However, given that its only the audio stream labels that are bad it seems much more plausible that TwonkyMedia could output a corrected stream, since this shouldn't involve transcoding. I would have thought that this would be in their interest since the 8621 chipset appears in a lot of products and recording DVB-T streams must be pretty popular (especially in Europe). Anyone from TwonkyVision support reading this?
I have not tried the ProjectX fix as documented in the link above. I will probably end up buying VideoReDo as it seems to do the job and has a nice batch option.

Hi again.
I'm using WinTV too with a WinTV-HVR-3000, so I guess I'll have the same problem. I've so far only recorded from the composite input, so I guess that explains why I've not seen this problem yet. I'll try it once I've finished my current recording.
I'm also using VideoReDo on a trail - sounds like I'll end up licensing it then!
Thanks for the info.

Of course an MPEG encoder is not used at all for recording DVB-T 
. My bad.
If you don't want to buy VideoReDo I have found that PVAStrumento (http://www.offeryn.de/dv.htm#pvas) achieves the same result and is free. Its also pretty fast.
