Snap with the latest nvidia drivers. Include the latest bttv2 and v4l2 drivers (taking out v4l from XFree86 config) and I am left, once again, with hgh cpu usage. Zapping reports that it is using "Video4Linux 2" controller, Bttv2 Video device name. If I fire up xawtv with -v 2, of interest: main: xvideo extention... Xvideo: 2 adaptors available. Xvideo: NV10 Video Overlay: input image, ports 58-58 Xvideo: NV05 Video Blitter: input image, ports 59-90 Xvideo: no usable video port found init: trying: v4l2... v4l2: open v4l2: device is Bttv2(0) - Video ioctl: VIDIOC_ENUMSTD(cmd=0xc0545619): Invalid argument ioctl: VIDIOC_ENUM_PIXFMT(cmd=0xc0385602): Invalid argument v4l2: overlay off So, presumably v4l2 can see Xvideo (hardware scaling?) but can't use it? I did try with -xv and -scale with no effe Any ideas? jg
