v0.98.13b fresh install with Terratec Cinergy Hybrid USB XS tuner (BDA recording plugin). Default/recommended settings throughout.
Config & channel tuning works fine, but the GB-PVR app crashes as soon as it starts (as soon as the main menu appears).
The only unusual aspect of my setup is that the PC is outputting to a plasma screen and I use PowerStrip to set a resolution of 848 x 480.
Anyone got any ideas..?
