I'm using Win2K, Huffyuv codec, WinTV-Go, and Virtualdub 1.4.10

I've been using the Huffyuv codec to capture from my tv card for a while, and I don't think I've ever run into this problem before.

I am capturing at 352x480, the using the 2:1 vertical resolution filter to reduce the video to 352x240. The original file is around 10Gb, and works fine.

After I convert, the resulting file is around 4.7Gb, but it will not open with anything after it's been converted. I've got no bad frames in the avi. I'm using the same codec, and I've tried a direct stream copy on the audio, and a full processing (uncompressed audio).

I know I've done this before, and haven't had any problems, but the last couple of things I've captured like this have had the same problems. Any ideas?

Thanks.
