Hi list,
as you may or may not know, new 2.6 series kernel dropped the "old" bttv 0.7x 
driver and uses 0.9x instead, which main feature is (I think) v4l2.
I have tried it last evening, capturing a star trek show from a vhs of mine, 
but it gave pretty bad results. I get lots of B (and S I think) frames, 
particularly in the first 3-4 seconds, and then I have other B, but not that 
much, for all the lenght of the work. 
What's really weird is that this gets worse if I lower resolution, by using 
the scale filter: I capture from bttv in 768x576 and then scale to 352:288. 
This way I got tons of Bs even after the initial 3-4 seconds, and the 
resulting video is unwatchable. 
Now, I know maybe mplayer needs something to work well with this new driver, 
but can someone confirm this?
