For the PC I'd look at SONY VEGAS and back on the MAC go get a demo of Final Cut Pro HD.
I have a nice new system coming I need to get some DVD Authoring software for. I'm looking for something that makes it really easy to make montion menu and really nice looking dvd's.
My friend showing me IDVD on the mac and I loved it. I've even thought about buying a mac just so I can use it. That's just silly so I'm hoping someone can lead me to a PC version that's comparable to IDVD.
I liked on IDVD how you just drag and drop things and it came with all kinds of cool templates that made it so easy.
