I'm using Vegas 4.
I've noticed that when I render as MPEG-2 separate streams, that last character of the file name I specify in the RenderAs dialog gets truncated.
For instance, if I enter "TheChoice" as my file name, I will get a TheChoic.m2v and a TheChoic.mpa file in my target directory.
Not a big deal, of course, but wanted to make sure it got reported.
