Hi,
I to had a lot of problems with PD8 & PD9 crashing and not being reliable, but upon getting a new high end computer and graphics card I can proudly state that in over a year PD9 has been extremely reliable. Only occasionally would it simply stop working, but not a problem with constant saves.
I was working only with HD files and taking full advantage of the Fix/Enhance and Power Tools options and upon either Producing these Projects or creating BR disks it NEVER in over a year did PD9 fail to Produce or create my disk successfully.
I just recently upgraded to PD10 and still very impressed with the reliability, so for me anyhow I deem my success with having a computer and graphics card that can adequately handle the task. For me there really is not that much worth considering in PD10 unless you want 3D which I currently don't.
