I've already got mythfilldatabase populating the schedule from RT, with the
correct channel numbers and even some icons.

I'm not too fussed about MythTV actually changing the channel at the moment
because I know this will involve scripts and an IR blaster.  I'm more
concerned by the fact that when I type in the channel number, or press up or
down on the keyboard - it just pauses and then shows me the same on-screen
information.

I don't know if I'm making much sense or not - basically since the feed from
the Sky Digital box is "just a video feed" Myth will have no way of knowing
what channel, frequency or whatever the Sky box will be running.  I do not
need Myth or my PVR card to do any tuning at all, the coax connection is not
even used - I just want the OSD and TV guide to reflect the change in
channel (in other words, if I type in 301 - I want it to switch to Sky
Sports 1 on the OSN and TV guide, irrespective of whats being shown on the
screen (as that's a separate configuration issue imo).

Hope I'm being clear - I know it's a slightly confusing scenario.  It would
probably be easier if I was using a DVB card, with the Sky signal being fed
directly into the card in the PC - but then I would only be able to view
Free-to-Air channels (all premium Sky channels are encrypted and require the
STB to decrypt).

Thanks again,

Darren
