Nice product but closed source and when they get out of beta I suspect
you will have to pay for it. It may or may not be worth it.

It must check home too as periodically I get a message "this version
is out of date, you must update" or words to that effect.

As far as just ripping a dvd, try:

mplayer dvd://n -dumpstream -dumpfile mydvd.vob

where n is the title you want to rip.

Then you can use avidemux or handbrake to transcode if desired. I
prefer h264 in a mkv, it comes out much much smaller.
