DVD's are 480p, you would have to transcode 1080i to 480p - a huge reducing in quality. With DivX you would transcode to 720p. Studies show that you only start to notice the difference between 1080p (not even interlaced) and 720p on 50+ inch TVs.
Not to argue, but converting to 720p may involve a 24 hour transcode to make a single DVD. I'm just guessing about the time factor... it might actually turn out to be more than 24 hours on my Powerbook G4. Simply writing the 1080i MPEG2 files out to a DVD disk with a few menus would put considerably less strain on my CPU and would reduce the frustration that occurs when the processs crashes 23 hours into a transcode. Granted, only HD capable media players could handle 1080i MPEG2 DVDs, but such players are becoming widely available. My I-O Data LinkPlayer2 has no problem at all handling 1080i MPEG2 files. If I could just find a burner that would put those files on a DVD, instead of having to play them over my 100baseT network, I could clear out a lot of hard drive space.
Clearly Apple is losing the race to provide the first truly accepted HD format. They bypassed MPEG2 for MPEG4 Layer 10 (aka H.264), thereby reaching for the stars while the mainstream has been moving in another direction. I have nothing against DivX except the transcode time and the (perhaps slight) loss of quality that results from a transcode. Still, it's a slap in Apple's face that Roxio isn't offering any H.264 option. H.264 capable players are soon to be released by I-O Data and some other companies. It's also a shame Roxio isn't offering a direct MPEG2 write-to-disk option that would constitute true EyeTV support, IMO.
Here's another question: Will Toast 7 be able to transcode 480i DV to DivX-DVD format, or to burn DVDs from previously converted 480i DivX files? This could be a boon to the home video enthusiast who hopes to squeeze more than 90 minutes of their family camcorder recordings onto a DVD.
