Is 15MPS too fast for some Blu-ray players? Any other tips would be appreciated.

Blu-ray players are capable of playback bitrates of up to 40 Mbits/sec.

I haven't rendered & burned Blu Ray projects yet. Any tips on the other settings that I should do for BluRay?

I'm having some problems burning .iso's in Vegas 8. When I am finished with the project, I tell Vegas to burn the .iso. When it finishes, I then tell it to burn the .iso. When I got into the dialog box to change the name of the file, it won't take it and changes it back to Untitled.iso. I've created new .iso's since then and now when I try to tell it to burn one, it wants to go back to the Untitled.iso. Does this make any sense?
