Hi. I can't get the pvrinput plugin to work with NTSC.
even though my channels.conf has 4 KOMO;KOMO:67250:I0C0:C:0:301:300:305:A1:996:0:0:0
the 'I0' does not seem to select NTSC. I think the picture is being recorded is at 720x576, 25fps
if I do a 'vdrsync.pl -i 001.vdr' the video file created reports: 'CCIR/ITU PAL 625, 4:3, 25 fps'
if I get mplayer to play the file directly 'mplayer 001.vdr' it reports: Playing 001.vdr. MPEG-PES file format detected. VIDEO: MPEG2 720x576 (aspect 2) 25.000 fps 6000.0 kbps (750.0 kbyte/s)
There's also no audio.?
Does pvrinput support NTSC???
I think it should, from what I've read in its documentation and sources. The TV norm seems to be only set by the inversion field in the channels.conf entry, so you have to specify your "I0" (take care of the syntax, I don't know if it matters if it's before or after "C0". You should also set "Frames per GOP" in the setup menu or setup.conf entry of the pvrinput plugin to 15 for NTSC (for PAL I think it's 12). And I also think I found a bug by grepping after tv norm and stuff in the source, please also apply attached patch, I think the frame size was always set to 720x576 which can never be NTSC. I also guess you patched your VDR for NTSC, so maybe it just can't playback your pvrinput stream if it's looking like you described, be it live or recorded, as it seems to be PAL...
Patched VDR for NTSC? Nope - I must have missed something??
I had been using VDR in the UK for several years before moving to NTSC land. The PAL recordings I made there do play back ok - just the new stuff recorded with pvrinput fails...
Try these, maybe it helps, but I can't guarantee, as I'm not the author of pvrinput, and I also can't test with NTSC.

Thanks, I'll have a play with the provided patch.
