Dvd shrink

Can some one please tell me how dvd shrink compresses files,
Is there a ripper that creates the 1/2 size dvd format 352X576,

Its all done quickly, with fog & mirrors :bigsmile: This is a very complex issue, suggest you start with some reading on their homesite.

Both DVD ReBuilder (for extras only) and DVD2SVCD have 1/2 D1 options.

Thankyou for your assistance.
