I've been using Vegas 5 for several months now and have never experienced a flash frame - either black or white - until my latest project.
I've done long projects (1hr 15mins) and short ones (15mins)...simple renders (straight VHS capture then render to DVD) and more complicated things (composites, etc.)
Only in my most recent project am I seeing problems, and the ONLY thing I can think of that I've done in this one that I haven't done before is use CTRL-SHIFT-F to close opens spaces left in tracks during the editing process. Not saying this is the cause, but it might be a clue.
