Use Composite or S-Video instead of RF Modulated output from your cable
box.  Then, you don't need (can /not/ specify) a preset channel.

Some have reported similar behavior.  I'm still of the opinion that the
behavior is a result of misconfiguration, but I haven't done any testing

Though if you get it to work, it's likely to only affect the first
recording, so you'd have to reboot between each recording.

Best bet is to use Composite or S-Video.  They will /both/ give you much
better quality, anyway.
