Hi Deb! Thank you so much for working on this, once this is merged we can finally get rid of the old videobuf framework. I did an initial review and found a few minor issues. In the meantime I will be testing this series with some of my bttv hardware this week (I hope). I will especially check for PAL support since you only could test with NTSC.
