Xbox Live On-Demand (OG Skate, Skate 2) Question?

I have a question for those who had physical copies of the games in the first place and then purchased the XBL On Demand versions.

What I am curious about is when you switched to the digital versions if your Saves, DLC, etc all carried over.

I know some games between physical and digital carry different "signatures" in the systems so saves aren't always compatible. Been thinking about buying all the skate series (don't think S3 is there yet, not sure) to have on my HDD just so I can be lazy and not have to swap discs when I want to play them, but I don't want to lose my saves and dlc rights. Thanks.

I'm pretty sure all it does is put the things you need from the disc on your harddrive
shouldn't affect your saves or previous marketplace data(s) as they are different things.

you'll keep them. if you've ever opened a savegame in modio it has your profile id and console id so aslong as those dont change (which they wont) you're good to go/

and even if you lost the dlc you could just redownload.
