Yes, exactly. There is a delay for buffering or processing or something inherent in the pvr card. There is no such delay through the sound card. I suppose the card could be broken. Sometimes they are. Any chance of taking it back to the shop and asking for another one? Or *cough* trying it in windows? I also wonder whether you should try either the mythtv-users list or the ivtv-dev mailing lists. Probably the first thing they will ask for is the log information from dmesg between these two lines: ivtv: ==================== START INIT IVTV ==================== necessary info ivtv: ==================== END INIT IVTV ==================== Just looking at this I see mine contains: tveeprom 0-0050: audio processor is CX25843 (idx 37) tveeprom 0-0050: decoder processor is CX25843 (idx 30) Also I note via lsmod that I have a cx25840 module loaded. Presumably that takes care of the sound. It may pay to look at your output - there are many variations of chipsets on these cards, particularly between PAL and NTSC models. > -- > [email protected] mailing list -- Nick Rout <[EMAIL PROTECTED]> -- [email protected] mailing list
