Once again, this is impossible. Really.

My CPU is a VIA C3-600 CPU, and its really too slow to transcode 
*anything*. If I force transcodung with -vf lavc=1000, the CPU load is 
99% and the video plays at 40% original speed only. Just decoding the 
mpeg2 stream eats up 75% CPU alone, without audio and without displaying.

Without forcing transcoding, the CPU load is 10% and no frames get 
dropped. This is roughly 25 times faster than with lavc=1000.

Cheers,

Udo
