Thanks again Colour for your help. Here's what I did last night per your instructions. Except I couldn't resist doing it all at once.
1) First I deleted all aux files... just in case.
2) Inserted Studio 10 disc and did the repair.
3) Installed 10.7 patch.
4) Removed Pinnacle Instant DVD and Pinnacle Media Manager server.
5) Restarted computer
6) Checked the background rendering but it was already enabled so I left it.
7) Deleted auxillary files again, the one file larger than 500+mb in the settings.vst file, and I also went and deleted the folder named Nathan which was one of the projects. Nathan was located if I remeber correctly in with the Render file. Not sure what exactly was contained there.
8) Started up Studio 10.7. I had about 8 projects (10 hrs worth of video) where I had already inserted all the clips into the timeline but no editing done. I think all that was lost, as I could open the projects, but most of the video clips and menus were grayed out or black.
So then I redid one of my quick projects (20 mins long). Inserted the clips, menu and transitions. The dark to light greens bars turned to yellow so quickly that when I was ready to save the project to Nathan again, it was done. So far so good. Then I went to the Make Movie tab. I chose my usuall settings, to DVD, and selected the re-encode entire movie, and render disc content but don't burn...just in case. The result was great, content rendered successfully, and then I burned it to a DVD. Friday night I'll have time to render and burn a couple more movies to see to help validate that the software is now fixed. I'll be sure to follow up later after a few smooth successful burns, hopefully with good news. Thanks for all your help in this.
I do still have a few questions though...when I first started Studio, I got a window pop-up that read, "Cannot load Adorage support-library/plug-ins" or something to that effect. First time I've seen The knowledge base tells you how to fix it (though I didn't try it yet). It doesn't however tell you what it means or does. Can you tell me exactly what it is and do I really need it.
I didn't check for errors, think I still should or let it go.
Do you think I should be ok in making my settings in Make Movie, "Safe Mode: Render content then burn to disc"?
How about the burn speed, what do you recommend as the best setting there, automatic, slow or fast, what do you use?
I don't really have clutter on my hard drive as I store all my photos on DVD's, should I still defragment?
Is there any danger in having to many projects at once?
Thanks again for your help!
