When you say you updated all drivers, you mean that you went to the nVidia web site and downloaded the latest driver from it, right? You didn't just trust Windows to update the driver. How did you check that all drivers were up to date?
What model of camcorder is your video coming from? What file format is this video and what resolution? Do you have Quicktime 7 installed? It provided components necessary for Premiere Elements 10 to edit certain video formats.
Thanks for your reply Steve.
Yes drivers downloaded direct from nVidia and latest update applied this morning.
The rest of the drivers (chipset etc) installed from disk and then updated.
I have also run Intel Driver Update Utility and everything is up to date.
Camcorder is a Sony HDR-CX730E. Format is .m2ts and the resolution is 1920x1080.
Yes Quicktime 7 is installed.
It may also be worth mentioning that we have just installed a trial of Adobe Premier Elements 15, and playback is working fine!
There's no reason that version 10 shouldn't work -- but it is a pretty old program, and you'll find a number of advantages to upgrading to a newer version.
That said, try one more thing with version 10.
In your Folder Options, enable Show All Files, then go to C:ProgramData/Adobe/Premiere Elements/10.0 and delete the BadDriver.txt file. (It may also be in C: ProgramData/Adobe/Premiere Elements.) Then restart the program.
If that doesn't do it, I'm not sure what's up. But I'm glad to upgrading to version 11 or later will fix it.
