Are you saying that in CapWiz, you cannot find where to adjust/change the captured bitrate

TDK1044 the DX2 is a hardware encoder. Machine power is not really an issue.

No i cannot find the bitrate option on capwiz, ANYWHERE heh, if you know where i can change it by all means let me know....

my cpu basics are intel pentium 4 3.2ghz/1 gb ram ill post more later im on the run, thanks!!

I'm using capWiz 3.6 (for an older USB Mpeg device from ADS Tech). So maybe they changed it?

If I hit the button on the top for VIDEO FORMAT, I can then select from 3 radio buttons (DVD Good, Better, Best). And also hit the Custom Settings radio button to select my own bitrate from a menu of choices). Is your CapWiz different?

Version 3.8 is more or less the same except the bit rate choices are only 4

Personally I always have the best results letting the hardware do its thing

from the manual: The chipset inside the DVD Xpress DX2 is always analyzing the incoming video and making adjustments to optimize the video quality and maintain the lowest bit rate possible. This is why there are only general video quality options instead of specific video bit rate settings.

I have capwiz 3.8, i can change the quality as posted above to 4 different types, but that does not change the bitrate from variable 8000.....i just did a test on all of them and the bitrate didnt change 8-(. Its still jerky on capwiz but its not jerky when i capture on vs9 on constant bitrate 4000. its totally smooth. also, i believe capwiz is frame based, im recording directly from my tv, isnt it better to have it lower first?

Thanks for all the help guys

The point is the DX2 is a hardware encoder. Does not matter if you use VS or Cap Wiz the stream out of the box is the same so both pieces of software are simply taking the same output stream and saving it to your hard drive.

when i record on vs9 i record it as "avi" format, mpeg comes out jerky and pixeled as well. When i burn it to dvd it looks good. I'd like to use capwiz, its just not working for me and i dont know why.
