will split it to 2 disc without quality loss and it's free.
dvd shrink is a good encoder, it is not a great one. Instant Copy 7 or 8 or CCe are great Encoders.
Most people (85-90%) don't notice the difference in quality, but there is a difference.
there use to be trade off in encoding DVDs. do you want great quality (a much longer encoding time) or Fast encoding (which resulted in horrible video quality)
DVD shrink bridged the gap by having great speed and great video as long as the movie is 6.5 gigs or less. DVD shrink sucks at encoding long movies. But, like I said, most people don't notice it
