If I use mencoder from the mplayer-1.0_pre6-r4 package to record a movie from my bttv-878 tuner card, I'm unable to record an AVI File without lots of dropped frames. On the same system, if I compile mplayer-1.0-pre6a myselfe, I can record movies without any dropped frames. When I observe the memory usage with the Top command, I can see, that the free memory falls rapidly to ~6MB. With my own Mplayer it remains at ~250MB.

Erwin, any luck with pre8? Also, you are recording TV video at a high resolution. Cutting it down even just a little bit will save you a lot of CPU usage.
Resolving as NEEDINFO .. Erwin, reopen or post a new bug if you're still having problems. Thanks :)
