For those that are interested, I've posted a new GB-PVR release over at http://forums.gbpvr.com/showthread.php?t=35528
You can find a list of changes on that page, but of most interest to people here is probably the much improved support for our Freeview H.264/HE-AAC system. The release also contains lots of other stuff like improvements to the Popcorn Hour client, improved support for the Hauppauge HD-PVR etc.
Post any support questions on the GB-PVR forums.
Thanks.
