I only tried this program with the VISTA operating so I can't speak for any of the others.
This program gets one star only because there is no provision for negative numbers.
The following problems were verified by Honestech tech support when I called them:

Screen capture files were unavailable to any programs other than the built in viewer. You can't print them or use them in any other way.

You can't single frame backward. If you overshoot the frame you were looking for you must use rewind to go back.

When using rewind there is no video, only a decrementing elapsed-time clock making it very difficult to find a particular frame.

When you do find a frame you want to capture you can't do a capture when paused, only when the dvd is playing.

The user manual references a "snaps" folder where screen captures are placed. The "snaps" folder doesn't exist. Tech support doesn't know where the screen captures are.

The only way to observe screen captures is with small, thumbnail, images.
Why make the capture if you can't use it?

The user manual contains information that, according to tech support, shouldn't be in there.

This program is not recommended for the VISTA operating system.

This software plays DVD's with 5.1 surround sound on my laptop, using my PCMCIA Creative Labs Audigy 2 Notebook audio card. That may sound trivial, but I have yet to get Windows Media Player 11 to do that, after trying every possible combination of settings. Several times. OK, maybe I'm too slow to find the right combination ... I don't care.

The simple interface (menu and context = onscreen right click) makes everyting immediately accessible. Unlike ... well, you know. At least InterVideo WinDVD (another software DVD player that came with my laptop I think) tells me it won't work (licensed only for 2 channel audio, send money for 5.1).

Its not like 5.1 sound just came out. Just buy this and save yourself the aggravation ...

This was cheap and does the job it was purchased for. So far so good!
