What is the best software you can get which can convert a DVD Frame to a Still DIgital Picture
There's really no best answer to that. The quality of individual video frames sucks anyway, but I don't think there's anything better than good old Photoshop to make them acceptable.
Have you already got the DVD frames captured and want software to make them look better or are you after software that will allow you to capture frames from DVD's?
Whichever software you get make sure you deinterlace first to get the full frame (assuming the film is standard PAL or NSTC)
That's my opinion. If you don't like it I have others
