[Automatic answer: RTFM (read DOCS, FAQ), also read DOCS/bugreports.html] Hi!
Took the original AVI, recoded it to very-high-bitrate MPEG4 with PCM audio (Hacking the audio sample rate on the origial with MP3 audio didnt work), plays fine, with no visible quality loss.
Then I hacked the header to an audio sample rate of 45983Hz (44100*(25/23.976)). (I hacked the videe frame time to 0.0400sec = 0x9c40, too, but mplayer didn't care, uses still 23.976fps; wonder where it gets this number from...).
The problem is your expression. Think for a moment: you want to play the sample faster and be perceived as 44100, so obviously the frequency has to be lower. So the expression is 44100 * (23.976/25).
Actually, we did the same thing. You went from 42294 to 44100, I did from 44100 to 45983. The error on my side was that I didn't hack the stream frametime. Looks like mplayer did interpret the -fps option very strangely; after hacking the avi to the right framerate of 25fps (found it in the AVI last night), the video syncs fine. But I won't open the champagne unless the SVCD plays in the DVD player... ;-) Ciao Martin
