    Apparently there isn't a special Blu Ray file per se, it's just that it allows you to use other files like MPEG-2 with much more data than a DVD will hold?

    Blu-Ray could be thought of as "SuperDVD"?

    Your post doesn't make any sense to me at all. There's no such thing as SuperDVD.

    BluRay must use the UDF 2.50 file system. Actually I think that UDF 2.60 is also valid, but you should stick to 2.50 for compatibility.

    If that is not what you mean then you need to explain better.

    Have you read the "What is: Blu-ray", up in the top left corner?

    Like other authored titles, DVD and BD both have specific subsets of file formats, which are usually in specific folder or sector structures. With DVD, the MPEG2 files are not just program streams (PS), they are packetized-elementary streams (PES) and labelled as .VOB. With BD, the VC-1, MPEG2, or h.264 assets (as well as the various audio & other assets) are encapsulated is standard MPEG transport streams (TS), but with specific sector sizes (M2TS, not MTS or TS) and lebelled as such.

    Is that what you're asking about?

    I believe MultiAVCHD, and possibly others, will allow you to create 'AVCHD on DVD,' which is - I guess - technically Blu-Ray on DVD... but it only allows for a short amount (runtime) of video, as you still can't write a lot to the disc.

    I'm just saying since it seems like it's just a matter of using larger files of the same file type, it could be thought of as a "SuperDVD".

    Then a 3 TB hard drive can be though of as a super-duper-huper DVD.

    But they're usually NOT of the same filetype. h.264 is the most common video codec used in BD and it isn't allowable in the DVD-Video spec. Similarly, DTS-MA & DD+ are probably the most common audio codecs on BD, neither of which are on DVD-Video. And PS/PES is not the same filetype as TS/M2TS.
    Folder structure is different. Filesystem is different.
    Yes SD material from DVD can be easily RePurposed to fit within the BD structure (without reencoding), but it still has to be extracted to the raw assets and then re-authored, plus there are a few gotchas...

    A hard drive isn't an optical disk.

    "Optical disc" is about the only thing that DVD and Blu-ray have in common.
