Hello all,

MythTV is almost too good to be true.

After couple of weeks I have a fully working system.
I've had my share of problems but I have solved them all.
Clues I read on the mailing list helped me enormously,
so I decided to share what I have learned to hopefully benefit someone.

1) Even after setting record on the line in, I did not hear anything. I
found a setting
called Igain (input gain) in Kmix or Capture in amixer that solved the

2) Us-cable frequency table did not work. Canada-cable did, but channels did
not look as good
as they should have. I got this resolved today. My ATI TV-Wonder VE gets
recognized by
bttv but the tuner was not autodetected correctly. I had to manually set the
correct tuner
in modules.conf. I got the correct tuner chip info by searching from google.
After this
us-cable worked and picture quality is great.

3) KDE takes up alot of resources. I could not record using 640x480 or even
480x480 without
getting some jerkiness and skipped frames etc. (1.1 Ghz Duron 384 RAM)
running under KDE.
Emerged (Running Gentoo) Fluxbox, and 640x480 was a piece of cake (well not
a piece of cake
but works 100% with about 90% occupancy.)
