I'm happy that analog tuning is working now. Do you have some suggestions
on what testing I should do beyond watching it? :)

Cool, that looks like it's working. I originally thought the
"TUNER_PHILIPS_*" was a text string and didn't realize it was a define.
That's why I thought I'd throw in the "NO_RADIO" just so it wouldn't
conflict/match another entry. Anyway seems good now.
As a follow up I'm having some issues with the ATSC channels on this card
(beyond the listings problem I still have posted on the mythtv-users list).
Occasionally the signal breaks up and/or stutters along with audio glitches
and pops.
I have a Core2 E6600 and when I'm playing live ATSC the cpu usage is around
44% but it's actually about 2% higher when I'm playing live NTSC so I don't
think the system is too slow. I thought it might be signal strength so I've
cut out as many splitters as possible and this card is getting the 2nd
cleanest cable I have (best goes to cable modem).
When I tune an ATSC channel with mythtv it says "Signal 0% | SNR 2.5dB |
BEXXX | LAM(lock)". The 0% part is what has me worried that I still don't
have good enough SNR but I haven't poked around enough to figure what other
people are getting for signal % and SNR?
There seem to be a ton of cx18 threads. Is there a guide for optimizing
settings for cx18? Or some general tips that might help?
thanks
