video outpacing audio?

I'm running the latest stable BetaPlayer on my rx3115 and trying to watch a movie I've just ripped. I used ffmpegX on my iBook to encode the movie, codec is XviD.

When I first played the movie, it gave me an error about the buffer size being too small--I didn't get this message while playing an hour-long file someone else encoded (not sure of the codec) yesterday, but I went ahead and increased the buffer size to 9600 (from 2400).

This allows the file to continue playing, but both before and after changing the buffer size, the video plays about ten times faster than the audio. This is reflected in the timer at the top of BetaPlayer, too--about one second into playback, it reads 00:10/2:02:39.

Any ideas why this would be happening? The file plays just fine using mplayer on my iBook, so there's nothing wrong with the file.

I have lots of files that play fine on my PC that struggle on my iPaq.

Although you say there is nothing wrong with the file - it had been encoded using a codec that you have on your Mac and so (logically) it plays perfectly on your Mac - but your iPaq may use differnet codecs and so it doesn't play fine.

Your logic that there is a problem with your iPaq is similar to saying that you can spend dollars in America but in Europe it is difficult to find places to take them - therefore there must be a problem in Europe as the dollars worked fine in America

I don't have a lot of experience using recent Macs (stopped using them about 10 years ago) but I would say have a look at the codecs used on your Mac and find out what work for other Mac users to allow them to play files on their iPaq (or any PPC) - then encode the file using those codecs so they will play on your iPaq.

I don't understand what you're getting at--it isn't some bizarre Mac codec, it's XviD. The file plays fine under OS X and Linux; I don't have a PC in front of me to test it, but I'd assume it works fine under Windows, too. I've never had a problem with playing files I encode with ffmpegX on Windows machines before.
