Also you may wish to take a look on www.videohelp.com
There are forums for just about anything video related, from format conversion, editing, burning, subtitle creation, players both hardware and software. A great resource. Also it has a great search database for video/audio tools. Some software titles you cannot get anywhere else (such as DVD Decrypter .. precursor to ImgBurn) are archived there. It's probably the best single multi-media resource I've found.
Everyone has their own preferences. I started out with Nero. I especially liked the tool for SVCD menu creation when I was messing around with that format. Very intuitive. But after a time I got tired of doing things Nero's way. So I got into using individual tools for each task in many cases. If you're relatively new to video conversions etc.. there's nothing wrong with starting out with it. But it can create hassles. If you do use it I recommend you not install the InCD portion, if it still comes with that. A headache waiting to happen.
I used Nero 6 Ultimate. But from what I see there's still need for a Nero uninstall tool. Which tells me some of the old problems still remain.
