Hello ivtv users! Im running a mythtv box with the ivtv drivers and wanted to ask a question about a problem Im having with the video part of a signal from cable tv.
Im getting some distortion of the video signal towards the top of the screen. Never had this problem before with all same equipment. A PVR250 on an AMD box using an abit motherboard. NVIDIA graphics card with latest NVIDIA drivers. To describe it best, It seems to look as white noise that runs horizonal from side to side along the top part of the picture and causes the vertical left side of the picture to bow inwards at times. Looks almost like an interlacing problem. Im running it on a panasonic 49" wide screen display. Im confident that someone here has run into something like this and can advise me as to what to check for. I did just a capture to file (cat /dev/video0 > /root/test.mpg) and its seems its not related to mythtv (ver. .19). But shows up in the test.mpg file as well as mythtv. Can I attach a jpeg image for an example to the group? 47k in size.
