I am using Vegas Movie Studio Platinum Update 6.0b to edit a 28:30 show that airs on a regional network. I am having problems with the program freezing mostly during preview. It happens after I have all program segments in place (all is fine so far). But when I go back and enter Text overlays with png backgrounds the freezing starts if I Play a segment to preview it. The program will come back to life after several minutes but then will freeze again when I make a change. If I check Task manager, Movie Studio is using 99% of the CPU time and the hard drive light is flashing continuously. It is strange that this only seems to happen when the text and backgrounds are added. I normally must add 20-25 different text/background segments in a show. Any advice would be appreciated.
