Version 3.0 won't run on Vista until you've installed the 3.02 patch. Have you done that?
Also, can you confirm that you "DV" videos are DV-AVIs captured over FireWire from a miniDV camcorder?
Yes, it's 3.02. I'm tempted to delete and reinstall, but I'm not sure
if I have the patch (I had a disk failure a while back and don't seem to
have anything like a patch in my downloads). If the patch is still
available online somewhere, a reinstall is what I was going to try
next. (Oddly, though, I seem to remember installing that patch well
after I started using 3.0 on Vista — maybe I already had that version
and the patch was something else).
I do not have a link for the PrE 3.0.2 patch, but it should be around. Before you do anything, I would download that, and Save it, so that it's handy.
Now, an uninstall/reinstall, then updating to the patch, might solve the issues, but if not, take a look at this ARTICLE on getting PrE and one's system/OS turned. Some of the OS links are for Win7, specifically, but some are also for Vista.
Thanks! I think you forgot the link to the article or it was stripped
"Also, can you confirm that your "DV" videos are DV-AVIs captured over
FireWire from a miniDV camcorder?"
I missed this in my earlier reply. Yes, it was from a miniDV camera,
using firewire. The only other odd thing is that I suddenly had trouble
with the audio and at one point saw a brief Windows driver message about
the 1394 driver being installed. The audio is being routed through a
PreSonus Inspire sound unit that is also connected via firewire.
However, this is a setup that has been working without a problem for a
while (a few years), with PE using the Inspire audio without a problem.
