Others have reported similar issues with EX1 footage. They've gone back to CS3.
So i installed CS3 PPro only.
loaded footage and it plays like a CHAMP!
Adobe why all the love for After effects and photoshop and flash and dw... and forget PPro?
I have a similar problem with HQ EX1 footage. in my case, the problem crops up when shooting lengthy events where the continuous footage ends up being split between two SxS cards. For some reason PPro CS4 has trouble after importing the long file into the project. The culprit seems to be the "importerprocessserver.exe". It locks up after importing the lengthy split clip and prevents further preview. PPro itself doesn't crash. Shorter EX1 footage works fine. It is strange that the split clip seems to import successfully, however the moment I try and preview it the "importerprocessserver" locks up and no further preview is possible (of any footage).
My workaround has been to move the folder containing half of the split file to another hard drive and import it separately. PPro no longer sees the split files as linked and imports them individually. When I do this I have no difficulty editing EX1 footage.
I'll be submitting a bug report on this today.
Thanks for sending this message.
Just FYI I installed CS3, did the update for it (150mb file) and EVERYTHING WORKS PERFECTLY .... SOOOO I guess the solution for me is downgrade :/
Yeah, one long continuous clip (2hr) and three different cameras, so three video tracks full of that
