Took me just 5 minutes to discover the first problem in Vegas 8.0b...
I have a HDV project (1080i25) with some animated maps in progressive SD format (576p25). When I render to AVC-HD (for blu-ray, i.e. 1440x1080i25) Vegas 8.0b crashes ("MS C++ library - Runtime Error") as soon as the process hits the sd clip. Vegas 8.0a "just" stalled at the same place.
BTW, rendering to WMV is working nicely with the same project.
