I used to be a fan of Roxio Easy CD but since their version 6 I have migrated to Nero and to date there is no complaint.  

Roxio's V6 was great for me, simple and easy to use. V7 was a great leap and V8 is even better!

Browse the product on their site and see if everything you want to do is in there.

The old Roxio's did have a lot of problems.  But, with the release of Version 7.5 they finally got their act together.  Both Roxio and Nero have just issued new versions - Roxio V8 and Nero V7.  Being so new there is no track record on them yet.  

In relation to the Sonic CD/DVD software, Roxio is now owned by Sonic and the Roxio V7.5 (that finally stabilized the product) has several Sonic modules in it. 

I have both Nero 6 and Roxio V7.5 installed on my PC, as I do PC support, and they both have pluses and minuses.  The Roxio has a lot more pluses and is a lot more user friendly than Nero.  At one time Nero was the choice of "techies" but as they have expanded the program and added more functions, they have taken a step backwards. I use both, but tend to use Roxio primarliy.

What type of DVD's do you intend to make?

If you intend to make video discs,  then you might want to look into one of the packages that is designed specifically to do video DVD's.  Some examples of these are Sony DVD Architect, Pinnacle Studio (v10 just released),  Intervideo WinDVD Creator,  and Sonic MyDVD.  I have used all of these for making video Discs and they work OK.  The Sony package does video disc's specifically,  and does it quite well,  but it doesn't really do anything else.  The other pacakges have the capabilities to capture video,  do some rudimentary editing on it,  then write the video disc.

If you intend to make data discs,  then just about every CD writing software will also write DVD's for you.  In this case,  find the one which you like the most.  Remember that Windows XP even has some basic functionality included to handle this.  I tend to use Nero for my data disc writing,  but I have used NTI, and a long time ago I  used Roxio.

Lastly,  if you are looking to make "backup copies" of your DVD's so that when your kids scratch them up,  you don't have to go spend $30-50 to get a replacement,  try looking at packages designed for that purpose.  Some examples of this are Intervideo DVD Copy, and DVD XCopy.  I have even used Alcohol 120% for this once...

Since I do a combination of all of the above,  I actually have used all of the software I've mentioned.  I tend not to try to use one package to do everything,  so I use the package that best fits what I'm trying to do.  Lately I have concentrated on using Pinnacle Studio to capture video,  Sony Vegas to edit it,  and Sony DVD Architect to author the DVD.  I also tend to use Nero for writing data discs,  and I used DVD XCop for most of my video disc backups (but I will use Intervideo if I am willing to soend more time to get a better copy).
