Yes but I have another issue here. I am new to this list so maybe you
know it...

When I try to cature some tv show with a line like this one in 388x284,
mencoder writes that it encodes at 25fps. So it's at full speed, no
problem here. But the problem is that it misses some frames.

I don't really know why, but I could not find any way to preven it from
loosing these frames. I even try differents video codecs to try to gain
some speed, but I still misses these frames.

On a side note, I have also the problem of sound in /dev/dsp with such a
card. When a v4l card says it has no sound capability, mencoder simply
disables sound, no matter what the options are. But this last problem is
probably known already (you can work around it by changing the source to
force it to encode sound, but it's not a perfect way to do it...).

Any help/info is welcome here...
