[MPlayer-users] video buffer full - dropping frame

[giorgio]

Hi to everybody.
I'm trying to record a movie captured by Hauppage WinTV USB but I get a 
lot of frames dropped and the output is actually a "sobful" motion picture.
I'm disappointed 'cause I have a good pc (Athlon 64 3200+, 1500 MB Ram 
DDR, 120 GB HDU for system (debian Etch) and 160 GB HDU for data) and I 
can't believe to get such kind of problems from mplayer/mencoder.
I tried also to compile mplayer from sources, but nothing has changed.
Down here the command string and the output related.
Thanks in advance,
Giorgio.
