How about
this list? (Oops, it didn't have Cyberlink Power Director on there!)
As Mark's said, the 'big 4' have 'pro' versions (like Canopus Edius is) - Sony Vegas Pro (ver 8 just out), Adobe Premiere, Pinnacle (Avid) Liquid (*see Senu's post below), and Ulead Media Studio Pro (although that's really a different program from Video Studio, rather than just a 'pro' version).
I'm a fan of Serif MoviePlus - which has excellent online support (forum + technical help) and I still think IMHO is the best balance of functionality and ease of use. Having said that it is now falling behind the competition (especially in terms of support for new formats especially high def, and its complete lack of 'smart rendering' which makes it less than ideal for MPEG (DVD) and again high def editing), and version 6 is eagerly awaited hopefully in the next couple of months, and hopefully with rafts of new features! It is also uncannily similar to Vegas (but with some pros and some cons versus Vegas Movie Studio Platinum) - so if version 6 isn't able to bring it back to the cutting edge of home video editing I might reluctantly have to resign myself to selling out to Sony!
Just for completeness, lucky Mac owners can of course use iLife iMovie or Final Cut.
PS (just seen your other thread): Serif is very good for dragging and dropping stuff (video clips, effects, transitions etc) where you want them, while the preview's playing, and making changes and seeing 'live' how they'll look - and you have to try pretty hard to make it crash (or put in too many quicktime movies!). But if you've rejected Vegas, even though I find Serif more intuitive than Vegas (maybe just because I read the manual for Serif but not for Vegas!), then you may not like it.
