[mythtv-users] Unable to watch TV, display issue

[Joseph A. Caputo]

Sounds like your tuner isn't set up correctly... either you need to change
your tuner setup, or fine-tune your channels.  Actually, based on your dmesg
output, it looks like your tuner card is not being detected correctly... the
driver seems to think you've got a PAL tuner.  Take a look in the kernel
documentation for the correct tuner type for your card (it's currently using
'19').  A good test would be to see what kind of picture you get with Xawtv.

Also, looks like your audio isn't set up right... either you've
misconfigured your audio devices, or some other process (KDE's artsd, or
esd) is grabbing the sound card.
