Description of problem:
There is no picture when running tvtime with custom compiled kernel
2.6.12-1.1421_FC5. It just says there is no signal. When running a custom
compiled kernel 2.6.12-1.1387_FC4, tvtime works as expected. There are no
warnings or errors displayed.

The video capture card is AVerMedia TVCapture 98 [card=13, tuner=5],
PCI subsystem ID is 1461:0004. There have been changes in the bttv driver
between the two kernel versions, but I'm not sure whether the breakage lies with
tvtime or with the kernel.
The platform is Pentium 4 @ 3 GHz (family 15, model 3, stepping 4) plugged in
ASUS P5P800 with BIOS version 1010.002, with Hyper Threading enabled.
Also happens with the stock 2.6.12-1.1421_FC5 kernel as provided in Fedora Core
Development repository. It's the first kernel where tvtime stops working (No
This might be the same bug as 146241. Channel tuning is broken in kernel 1411
and later. When you power up, the tuner stats on a channel with no signal and
you are unable to change to another channel.
Correction to #6. This might be the same bug as 162451 (not 146241)
