I've been writing a script to just poke all possible values into the various registers and see if i can get ANY change at all. So far, all I've been able to do is get either no audio, or both the tuner audio and the line input at the same time. I started with CX25840_SET_PATH1_SEL_CTL and so far the only value I've been able to find that gives any audio is 0x0002 Anyone fiddling around with the registers have any clues regarding audio routing? The only other two problems I'm aware of are the S-Video input is monochrome (at least it is on my card) and I haven't tackled the IR receiver or transmitter yet. I've read the receiver works, but I have not tried to get it going. > Thanks to everyone who has contributed to the ivtv and v4l projects! > Jeff > Yes, thanks to everyone working on this stuff...can't say that enough! ----- Jim Reese, WD5IYT [EMAIL PROTECTED] ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
