I tried tvtime but it was very juddery for me. The processor usage for it is: 2797 root 20 0 66352 20M 7464 R 74.8 5.3 1:15 X 3419 root 11 0 8252 8252 8000 S 13.4 2.1 0:01 tvtime Does it use Xv for scaling? My monitor's refresh is set to 75Hz. Could that be why it's so juddery? > - full-height/rate recording from consumer cards such as bt878 [3] I record at 640x480 with mp1e.

I have always thought the best way to get the same quality picture (smoothness-wise) you get from cable/air is to exactly record what you are getting and play it back as it was played originally, to interlaced devices. None of this field combining etc. b. -- Brian J. Murrell
