Hi Guys,
I was also having problems seeing the new HD channels with OzTivoExtreme.
I could see the new HD Channels listed in my Wiki page (
http://minnie.tuhs.org/tivo-bin/tvguide.pl) but my MCE wasn't picking them up. I got them working by editing the ChannelInfo file in C:\WINDOWS\ehome\BladeRunnerPro\QuickGuide. Open it in Notepad and add the HD channels into this file, MCE will then pick them up. Hope that helps a few users.
Just get ready to see lots of blank space in the SevenHD and TenHD channels as the SD programming is not listed.
Cheers
Kathlik.
