2 and merry Christmas.
Uninstall CS4 and run the CS4 clean script 2 or 3 times, re-starting your system after each run of the script. Reinstall CS4 and try again.

OK, I'll give it a try with Clean Script, even though I already tried it several times. In the end I'll reformat the OS and re-install everything. Now after many trials and errors, I may have found a clue that is worth exploring. Today, I noticed that Premiere seems to crash all the time at the same location when reading the timeline. At this location. there are 3 small voice-over audio files on Audio track #3. I removed these files, then Premiere worked fine till the end and more interestingly, I could export to AME and encode MPEG2.
This may be a clue to corrupt files. I don't know why they can be corrupt because they were recorded with Premiere voiceover, but we may have looked at the big picture while neglecting the small one. Is this possible?
It sure looks like it.
Thank you guys for your help. I really appreciate it.
