Thanks, I have downloaded it and added to my test collection. The problem with locking up seems to be related to DSP based audio decoding, when you run mplayer from console with -nosound option, it plays ok. And if you use -ac ffmp3 for mp3 decoding, it also does not lock up. Anyway, video and audio get out of sync pretty fast, seems like there are some problems with framedropping (it does not work) for flv files. It is an interesting file and I'll try to see what can be done to fix these issues.
