Can't find channels

Hi. I have tried MP today for the first time and can't tune the channels.

My TV card is a Nebula USB and the PC I'm using runs on Windows 2000 pro SP4. At first I installed the Nebula BDA drivers and made the DigiTV-USB-BDA.inf changes they suggest for win2k users. The card is seen by the OS as an audio/video/game controller and seems to be working fine. Then I installed the latest stable MP 0.2.2.0. I had difficulties in trying to edit the card and got the notorious "unable to create graph" error message. However, after seeking advice at a Nebula forum, I manually copied and regserved the stream engine files from XP. Now the error message is gone and the autotuning looks like it is working. However, it doesn't find any channels at all. I checked the frequencies used for my town and they seem to be correct. Also the signal strength should be OK as it was always reasonably good using Nebula's software.

So everything _looks_ fine, the tuning just doesn't find any channels. Any idea what to try next?

Thanks.
