Video but no Audio on Zire 72

[yoda845]

I am a newbie. I followed junglemike's guide to video/audio file conversion for a palmOne, a Zire 72. I took a video I own and copied it to my hard drive with DVDXCOPY. Then I used VirtualDubMod to convert it for vewing on my Zire 72.

The result was a file that played perfectly on my PC (video and audio) but only the video played on my Zire.

Here are the parameters I used for the conversion. Can anyone point me to the error of my ways?

Many thanks,

When I viewed the audio streams, there were two listed. I assume

that one was the movie itself and the other was the commentary:
Dolby AC-3 Audio (substream 0x80)
Dolby AC-3 Audio (substream 0x81)
So, I opened the 0x80 stream and chose these conversion

parameters:
SAMPLING RATE - 48000Hz
PRECISION - 8-bit
CHANNELS - No change (mono)

Do you have the AC3 Filter (http://www.doom9.org/Soft21/Filters/ac3filter_0_70b.exe) installed on your handheld device? If not, this might fix your problem.

according to those settings he doesn't need ac3filter :)

for everybody wondering, i guess you're talking about this guide: http://www.spug.net/showthread.php?t=57983

honestly i wholhartedly disagree with the method used in this guide. (apart from the fact that he is obviously violating copyright laws as he's using release group avis in his guide)

problem is, he only tells you how to convert an avi to a smaller avi, which is not really what you want to do when you've got the original DVD at hand. in your case, i think what you did is compress the dvd to a standard sized avi, then recompressed the avi to fit it to your palm. while this is of course one way to do it, it is far from ideal as you are unnecessarily sacrificing a lot of quality.

in other words, i would recommend you a very much different approach which is only mildly more complex than the one described in abovementioned guide, but should yield far better results.

so please take a look at the gordianknot/xvid (http://www.doom9.org/gknot-main4.htm) guide. it should provide you with all the information to do this video conversion right and as an added bonus, it is definitely up to date! (xvid 1.1)

just to sum up the pros of this method:
- should be A LOT faster
- better video quality (only one compression step)
- better audio quality (direkt ac3 to desired mp3 encoding with besweet)
- more advanced filtering methods through the usage of avisynth (which you won't notice) resulting in once again a better picture quality

ammck55 and killingspree,

Thanks for your replies. I attempted the AC3Filter installation but all I got was a PC installation, no palm.

Perhaps, your recommendation, killingspree, will solve my video-audio, out-of-sync problem. The video quality is excellent but the audio is out-of-sync by a number of frames.

I really appreciate all your help. This is actually fun, expecially with a 1GByte card.

P.S. Yes, killingspree, you pointed to the guide I referred to.
