I recently purchased the ADS expressMPX(?) which is a USB device to grab stuff into DIVX format.
I was quite impressed by the quality of the product (except it came with VS8SE which I quickly tried to replace with VS9) but I returned the device to get a card with a TV tuner.
It turns out the Hauppauge and the ATI cards I am trying right now have a lot harder time with PAL video input. This is weird because it is actually up to the software to determine the video input type but oh well...
MY FIRST PROBLEM with the DIVX capture is taht although the output files where supposidely using the DIVX 5 codec my one our movies where around 17GB!!!! What was I doing wrong?
MY SECOND PROBLEM Using the same capture mode on the two cards I am testing now I get pixelized output. This is probably due to the onboard MPEG2 encoder: the signal is encoded once in MPEG2 by the board then re-encoded into DIVX by the software. Anyone have a fix/idea?

WARNING - I've never used DivX. 
Lots of users have had problems using DivX with the Ulead products.
The Hauppauge cards are MPEG2 only. I have one, and the hardware MPEG2 encoder seems quite good to me, but MPEGs are not meant to be edited. Any editing other than cutting & splicing requires an extra decode/re-code cycle which will degrade the video. Worse, you can end-up with a corrupted MPEG.
Capturing analog video to MPEG without a hardware encoder is risky. MPEG encoding is CPU intensive, and if the CPU can't keep-up with the real-time video, you'll get dropped frames or corruption.
PROBLEM 1 - I have no idea.
PROBLEM 2 - Of course, converting from one "lossy" compression method to another (MPEG2 to DivX / MPEG4) will degrade the video.
You'll probably have much better results if you capture to AVI/DV, which isn't nearly as lossy as MPEG. Do all of your editing (if any) in AVI format. Convert to DivX as the final step.
