Lolly:Thanks JJN.
A few more questions!
What are Smartsound Discs? Is this the music available within Studio 10 or they special CDs
Smartsounds are provided by a different company to Pinnacle/Avid. Avid now provides Scorefitter, which does the same thing, but is "midi" based and doesn't sound as good (to many people). S10 came with Smartsounds and a relatively small set of tunes, so many people bought extra discs, and these don't work in Studio 14, you have to use another program.
If you think you will be using a lot of automatically generated music, this may be important, as S12 can still support Smartsounds
What is a "buggy"
I just mean the program can hang on occasions or doesn't do what you expect it to (as in "bugs")
Can I edit my old non HD video clips using S14
Yes
Does S14 Ultimate "hang/freeze" frequently?
That depends. On a fairly powerful, well set up system I find S14 no worse that earlier versions. On my laptop, S14 will hardly run the importer at all.
Other peoples milage may vary
