I have to admit that just the ability to boot off a USB stick is pretty cool.
The only reason that I was trying to boot off a USB DVD was in order to perform a recovery using a Vista install DVD. In the end, I did not even need that... EasyBCD allowed me to recover everything all by itself.
The thing about PLoP is that the author is trying to get USB CD/DVD booting working.. just check out the changelog. Perhaps it would be better to leave things alone, keep an eye on PLoP, and then think about updating PLoP within EasyBCD v2.0 when appropriate?
