My last computer died in the middle of an important video project. I purchased a new HP computer built for video editing. It runs on VISTA 32 bit (but has upgrade available for 64 bit). I upgraded from Studio 9 to 10.5 and the menus would not drop onto the timeline, so I upgraded to 10.7. The menus now drop onto the timeline, but are not interactive when one burns to DVD or even using the "create content but don't burn disc" format. I have been wrestling with this for over a week--going on two weeks. Does anyone have any ideas to get tne menus to work (loop if a chapter/page not selected or go to a selected chapter)? By the way, the BETA 10.8 doesn't work. It has expired, even though I've been told it hasn't. I get the error, "this BETA has expired..."
