Sometimes Premiere Elements doesn't save its renders. So what you're experiencing is consistent with what many are.
The solution to the bad display driver is in our FAQs to the right of this forum.
Windows 7 64-bit is also notorious for causing buggy behavior in a number of 32-bit video editors.
Also, per the big announcement at the top of that web page, please do not post questions to the FAQs forum. We're trying to keep that forum purely reference topics.
A remarkable answer. After all we are talking about PRE version 9! Imaging that Microsoft would tell us that Word occasionally forgets some characters or words of our text files.
And wouldn't it be fair to say that PRE 9 has problems in Win7-64 because it’s 32 bits and not vice versa.
If you're upset with the software, I encourage you to make Adobe aware by publishing a bug report and feature request. There's not much more we can do for you if this is a dealbreaker.
As I'm sure you know, we don't work for Adobe. We're just fellow users trying to help people out as best we can here.
Have you checked out Premiere Pro CS5? It's designed to work on a 64- bit operating system.
Dear Bill and Steve,
Please don't take my questions/remarks personal, because they are not.
Giving the fact that many people have problems with the rendering makes it an Adobe issue.
And on the website they don't restrict PRE to win7 32 bits.
I was happy with PSE-4 so I changed with no doubt to PSE-9 and I expected the same quality with PRE.
My mistake and unfortunately my 30 days are already gone.
