I'm looking forward to trying it out although I expect it to be a pain, I plan on following this:
Final Cut 2 -> Toast 9 -> Blu Ray (on Dvd) -> Ps3 -- Working - Roxio Community
I think that you should be exporting as pro res, exporting HDV is not the highest quality as HDV actually loses quality when you edit it. There are posts about this but all you have to do is change you sequence settings to PRO RES at the last minute, and when you export your reference or self contained movie the video will actually look better. HDV is a nasty nasty codec, and I would only use it to capture and edit because it's quicker on my machine.
If you don't have Pro Res maybe Apple Intermediate Codec works in it's place?
