DVDxDV is a very useful tool, when working on DVD material to be edited, even in iMovie!
Several weeks ago, i started editing a EUS31 DVD proyect with a low budget in my pocket. i went to the internet looking for a good converter,because most of the footage were burned on DVDs.
I try de Demo, and found it useful and stable. with excellent image quality.
Days later i bought a SONY DVD/VHS recorder, and found that certain DVDs like the one´s burned in this device, can´t be converted without using first some comand-line technique or in my case, a Rip Software.
You have to get used with the program Preferences to get rid of audio sync problems that sometimes happen, and/or intelacing issues. But this depends of footage quality in most cases.
Anyway, i´m happy with this great tool.
It works fine for me.
