Same question here.
I have a avermedia studio 303p remote control, but this is not a BT88 card but equiped with a Philips Saa117x chip. It will not work with any plug-in a found until now..
(although there might be to many plugins to chosse the right one from..)
Here is a guide I made for Hauppauge WinTV. It's a PDF File. Fully Customizable Controls using the INI file that the remote reciever uses. I have to break it into 5 files to make it uploadable, so download parts 1,2,3,4, and 5.
