Hi all, I have a similar problem to the OP, and I'd love some help. I've been producing home movies for years, started off with an enormous JVC VHS C and an analogue vhs mixer straight to VHS....
A couple of years ago I went HD and tapeless - bought a Sony TG3 AVCHD 'FULL HD 1920x1080i'. I'm just making home movies of holidays, the kids, and stuff like that.
I'm recording to SD card in HD, exporting into iMovie09 where I edit my material. Then I either export to iDVD, or Toast 8 - seems to make little difference which.
The DVD that I end up with is very blocky, and unsatisfactory. It looks nothing like the actual footage on the SOny TG3 when connected directly to the TV - there it looks stunning, on the finished DVD it looks truly awful. Its difficult to put into words - the motion isn't smooth - it reminds me of trying to watch after a few beers, or with a hangover!
I've spent the past 2 years picking my summer 09 holiday movie up, getting irritated with it, leaving it, coming back and starting over. Its very disappointing. Please if you have any ideas, I'd love some help.
Thanks in advance,
Peter
