I have no problems changing the channels (with either the WinTV remote or 10-key on my keyboard) when I am watching live TV.
My Direct TV service has only three digit channel numbers. However, the satellite receiver, Philips DSX-5500, shows the channel as three digits followed by a dash and then two more digits.
So if you use the Philips remote and punch in 1234, it will give you channel 123-40, which is not the same as 123-00, which is a real channel. If you were to punch in six consecutive digits (123456) and then enter it would give you 123-45, 6, with channel 6 as the channel showing up on WinTV.
This would not be a problem, except for the way WinTV scheduler keys in a channel to be recorded. As I said before, if I am watching channel 123 and want to record 456, at the time a recording is initiated WinTV Scheduler/WinTV keys in the current channel followed by the channel to be recorded. So in this case, it would show on my TV the WinTV scheduler keying in 123 and then 456, which shows up as 123-45, 6 - meaning that I end up recording channel 6.
I guess a general question is
a) is this standard with WinTV - that Win TV Scheduler/WinTV re-keys the current channel throught the blaster before keying the channel to be recorded?
b) is it standard with Titan TV that if I select watch from the menu then Titan TV sends a message to WinTV to key in the current channel 3 times prior to keying in the channel that I want to watch?
Also, a related question - when I close out WinTV and then reopen why does WinTV always revert to a default channel. In my case, I am watching channel 202, close out of WinTV, then reopen WinTV - for a split second I see channel 202, then WinTV keys in 005, which seems to be the default channel when WinTV is opened?
