I purchased plantinmum 6 a few years ago after I discovered Cinestream was not supported by XP. After that, I did no editing until recently. Now I find there are a few editing difficulties with version 6. They may be bugs, or just my unfamiliartiy with the program. At any rate I am finding this more difficult to use to edit than Cinestream, which I felt was quite capable. I am considering upgrading to a later version, but can't find comparisons between ver 6 platinum and version 8 or 9. Can someone who has used 6 please tell me the main advantages of the newer versions? Also, is 9 significantly better than 8? The upgrade prices seem very reasonable, but I don't want to upgrade to something that I am going to find gives me the same problems.
