[mythtv-users] Any way to tell which tuner card might be bad?

[James Pifer]

I have a myth system with a PVR150, 250, and 350. My system is several
years old. For about the last month, maybe two, we've had recordings
with consistent "bad parts" where the video will skip and sometimes you
see distortion right around the skip. Watching a show this evening my
wife was very upset!!! 

Anyway, I don't know if it's all the cards or just one or what. My myth
server is an old Dell Poweredge 1600 with plenty of airflow. It's in a
closet, but the closet has airflow and general stays at a decent temp. I
just opened the server and stuck a fan next to it blowing more air on
the tuner cards. Time will tell if that helps. 

I saw in the archives from a recent thread that someone suggestioned
checking the heatsinks. Everything on the cards appear ok. 

Is there any way to tell what tuner recorded a specific show? I could
try and keep track and see if it seems to be a specific one. 

Looking through the backend log and grep'ing for "Error" I found errors
like:

2010-02-08 16:01:15.791 TFW, Error: Write() -- IOBOUND end

socket went unconnected.

I'll have to look through the archives about tuner cards since I know
it's discussed a lot, because my wife even said, how much is a new tuner
card?.?.?. Not sure what I would get since I don't do HD and have no
immediate plans for it.

Any suggestions are appreciated.

Thanks,
James
