Well I've seem to have cleaned up the picture a little bit by changing the following playback settings for MythTV:
I am deinterlacing the playback with the Kernel algorithm and handling mpeg 2 with libmpeg2.
When I use these settings am I allowing the on board decoder on the card to function or am I passing the work on to the CPU?
Though it cleaned up the blur/shakiness there is some really light rectangles that pass across the screen from right to left behind the picture? hopefully I can modify some config to clean that up too, so I guess I'll just keep playing with the various playback options and see what produces the best quality.
The only other problem I am having is displaying surveillance video from the component input. I've followed the instructions in the wiki for an analog cam and a bttv card, trying generic & hauppauge for the manufacturer with the motion wrapper. I also added a generic analog cam to be controlled through the motion wrapper using input ports 0 - 3 but still no dice....If anybody has had success with one of these WinTV PVR with an analog cam over the component input or the s-video in(I have an s-video to component adapter so that would work too) I be very interested to see the settings that you have used, or if there is a wiki article that deals with this issue that would be great too but I can't find anything that is terribly specific. Any suggestions would be greatly appreciated.
