I haven't taken the Blu-Ray plunge yet, but I was just wondering if a typical DVD-compliant MPEG-2 is compatible with the Blu-Ray format?
I just thought that if I had some MPEG-2 files that were originally intended for DVD, it would be nice to be able to author them onto Blu-Ray in the future if I wanted to.
I don't know if there is anything different about Blu-Ray that requires MPEG-2 to be encoded/formatted in a different way?
Thanks in advance.

Yep, you can put 720x480 29.97fps and 720x576fps MPEG2 on a Blu-ray video disc. Read also https://forum.videohelp.com/topic346387.html

Some authoring programs may not enforce this, but I believe that technically speaking 50 or 59.94 fps are the only valid frame rates for DVD compatible video on BluRay. Please confirm that if you can.

I've had no problems doing this with DVD, so it's kind of hard to believe you couldn't do this on Blu-Ray. -
I confirm this since I have had the privilege of having a friend who works with, and is knowledgable with, Sonic Scenarist.
Any video stream that is DvD compliant is easily accepted by Scenarist, which is the "benchmark" software for blu-ray compliancy.
However, believe it or not, you will come across an AC-3 source that isn't accepted. Scenarist is more picky about audio than video for DvD sources. (There are a few encoders though that guarantee this compliance if re-encoding is necessary.)I hate VHS. I always did. -

HD-DvD allowed smaller resolutions, such as half D1, even VCD rez, several fps (29.97, 23.97, pulldown), etc. The only way to play these on blu-ray is through the DvD feature (or with any other features that may exist outside the blu-ray standard like DivX, MP3, etc.)I hate VHS. I always did.
