can't record HD

[sjpvr]

I have an ATI HDwonder card configured with 2 analog tv cards. I can watch live HD tv, but when I record, it opens up an activemovie window showing the program is should be recording, but only creates a 0mb .mpg file. I have no problem recording SD tv. Any ideas?

Thanks.

I think you will be asked for more info: specs and logs.

What version of Windows are you running?

Waht is the output of MuxChecker on your machine?

Its usually the mux that is responsible for this. Which mux are you using and what version?

The Microsoft DVR-MS mux seems to perform the best with ATSC HDTV.
