Hi Neil

Thanks for the response - sounds like you've been busy!

Would still like to see your skychannel script / collate script - it 
sounds like you have a very similar setup to me - UK+PVR250 etc.. if you 
wouldn't mind sharing - I'll look through the list for the last month 
and see if I can find that version too.

Out if interest where did you get a cheap LCD in the UK? not been able 
to find one that I can easily integrate.. not sure if it's something I 
actually want but would be interested (my silverstone case covers all 
drives so probably isn't practical)



P.S. and your script is *still* more reliable than anything else I've 
found - and a couple of days ago I switched to SVN - and to be honest it 
feels like channel changing is even quicker with SVN/your script.
