USB-UIRT Forum

I have a Windows XP computer, Hauppague PVR 250, with GBPVR 1.1.5. When I have GBPVR set up to not use any channel changer, it records fine. However, if I set GBPVR up to use the USB-UIRT channel changer, all my recordings stop after about 1 minute, sometimes 5 minutes. I've posted at the GBPVR forums, but they say it isn't a problem with GBPVR. I've tried the 1.4 and 1.3 drivers, but both still did the same thing. I have no idea what may be going on, but I'll really appreciate any guidance you can give me. What can I try in order to fix this problem?

Thanks!
