Hi,

I have a Pinnacle PCTV Pro TV Card on my linux box running ArchLinux (Kernel 2.6.23).

The first time I managed to run KDETV, the picture signal was clear and I could tune in many channels.

At that time I am sure the TV Card was being auto-detected.

Because I was struggling with getting the sound working I tried out several things I read on some LinuxQuestions posts. One of those things was running xawtv to try to unmute the sound.

The first time I ran xawtv, the tuner picture appeared as fuzzy/grabbled, basically as if it was not able to find a signal or as if it was in an-out-range frequency or something.

I ran KDETV right after that and to my surprise I found the same problem...which was weird because it was running fine just before running xawtv. I don't know if this was coincidence or not.

Anyhow, in the meantime i looked for some solutions to this in some posts and someone suggested this might be to do with a wrong tuner being selected by bttv.

I looked up the tuner in my TV Card and matched that to the tuner no. and configured it in my modprobe config file.

I can see in "dmesg" that it is picking up the card I specified. However, now the issue is random.

I restart my linux box, start a channel/frequency search in KDETV and sometimes I manage to pick up some channels. If I stop there and restart KDETV those channels appear correctly.
But then if I later ever try to scan some additional channels on higher frequency ranges and it reaches the fuzzy picture range all the previously configured channels stop working again...

I also have not figured out yet how I sometimes manage to reset this issue. I am not sure if it's when I change the tuner no. in the modprobe file and restart my linux box or something else...

Anyone experience this problem? Any recommendations on how I can troubleshoot this problem?

Let me know what outputs you want me send you to help. "demsg" or lspci.
Any help would be appreciated. It might just be something obvious I missed.

Thanks...
