Hello!

Recently, I have buy 2 Formula one Motor racing VHS. I try to capture it by Virtualdup and get the following result:

I capture at 384 X 288 using DivX 3.11 alpha and MPEG Layer 3 to compress video and audio.
For tape 1, I can capture at 25 fps without framerate drop while for tape 2, the framerate drop a lot to around 15fps!!!

Then, I try to capture at 320 X 240 for tape 2 and no framerate drop at all!!! So strange!!!

Why different tape can cause different result in capturing with same setting? So confusing! Anyone know the reason?

Thanks a lot!
