Mike, I'm pretty sure they're talking about the CHANNELUP/DOWN actions
as handled in TV::ActivePostQHandleAction().  If not watching live TV
nor a DVD, the code makes CHANNELUP/DOWN behave like JUMPFFWD/RWND.

Personally, I want all of the hardcoded overloading of actions to go
away so I have more freedom to map keys to actions the way I want.  As
it stands now, I have to modify the code (just like the OP) to do
that.  For example, I too have commented out the DoSeek()s in the
TV::ActivePostQHandleAction() CHANNELUP/DOWN handling so I can use my
channel up/down keys for something else when not watching live TV or a
DVD.  In all, I've currently got 8 separate changes in my local
tv_play.cpp to achieve my desired key handling.  I'd like to get rid
of them all someday.
