"F" is only active if you've turned on this feature. Go to
Setus->TV Settings->Playback second page and check "Use Xv
picture controls".

Knowing the characteristics, I seriously doubt these will
give you a good picture. You may want to check the settings
on your TV and grab some test pattern images off the web to
check your TV out picture before making these changes to your
tuner signal ahead of recording. Once the recording is distorted,
you can't fix it by compensating during playback. But, it's
your machine ;-)...

update channel set contrast=32768,brightness=32768,colour=32768,hue=32768;

Will change all channels at once. The above will reset the defaults.

Small adjustments to the frequency.
