Help why can't I open or drop M2V files created in Vegas 8c back into Vegas 8c?

Help...

Help!

If I try to import any Blue Ray File created by Vegas I now get a "unsupported format error".

I have current Quicktime, Windows Player 11.

The same Blue Ray Files will open in Nero!, but not Vegas 7d or 8c????????

I tried deleting the cfhd.dll file.

The M2V files play perfectly in all players. Vegas just won't recognize them.

If someone has a solution, I would like to know as well.

Vegas Movie Studio 9 has the same issue.
It will not play with M2V files.

I found out using Pinnacle Studio 11 to capture video direct to laptop.
I got back to my main desktop machine, fired up Vegas Movie Studio and...this is a no go.
To say the very least, it was not a happy moment.

I just edited a M2V 1440 25 MBPS file created by Vegas 8c in NERO Vision!!!!!

Neither Vegas 7d nor Vegas 8c could recognize the very existence of it's own M2V file!!

Frustrated...
