Been running BTV 4.2 a week or so now, upgraded from 4.1. Everything has been working great. Then sometime yesterday Live TV and recordings quit working.

Tried running the BTV Setup Wizard several times, removing the tuner, changing the lineup, etc, etc, and it'll never pass the test (no picture or sound) and I get the error noted. Yet the tuner is detected okay, and an AutoScan finds the correct channel lineup. Uninstalled 4.2, went back to 4.1...no joy there either. Uninstalled the Haup driver, reinstalled, doesn't find any newer drivers (and yes I'm using the SS Haup drivers for the 150). Tried updating DirectX, already at 9.0c, no joy there. Have tried 3D/Hardware vs Overlay...zilch. Have rebooted several times.
So basically my BTV is dead in the water for no known reason. I made zero changes to the system...it just broke. Ideas appreciated, else I guess I'll have to go the TS route here.
