I am trying to capture from Saturn TV (cable) here in New Zealand and the only way I seem able to get a picture is from the composite output from the cable box. All attempts to get any kind of picture from the tuner input on my card output from the cable box's RF output result in static. Although I can get a picture OK from the composite input, its very blocky in MythTV. It appears to be fine if I simply cat from /dev/video0 and play it through mplayer though.
Anyone out there have any tips on how I might improve the picture quality? BTW, I should probably have a go at trying out the tuner with Chris Kennedy's latest driver (0.3.2m). Will re-post if I have any luck. For the record, my modprobe.conf is very basic as recommended by Jarod, consisting of: # ivtv modules setup alias char-major-81 videodev alias char-major-81-0 ivtv options cx25840 no_black_magic=1 Output from loading Chris Kennedy's latest driver is : Mar 25 11:49:17 rimmer kernel: ivtv: ==================== START INIT IVTV ==================== Mar 25 11:49:17 rimmer kernel: ivtv: version 0.3.2 (m) loading Mar 25 11:49:17 rimmer kernel: ivtv: Linux version: 2.6.10-1.770_FC3 686 REGPARM 4KSTACKS gcc-3.4 Mar 25 11:49:17 rimmer kernel: ivtv: In case of problems please include the debug info Mar 25 11:49:17 rimmer kernel: ivtv: between the START INIT IVTV and END INIT IVTV lines when Mar 25 11:49:17 rimmer kernel: ivtv: mailing the ivtv-devel mailinglist.
