As well as the extremely long render times I have encountered (http://forums.adobe.com/thread/1330417?tstart=0), I also now have no option of exporting to Mpeg Blu ray from CC 7.1. When I select Mpeg blu ray going through AME it changes the format to an .aiff file!?!!?
This is the worst update I have ever recieved from Adobe and I have been using premiere for 15 years.
Adobe: please can you msg me on how to roll back to 7.0.1. It was nice and stable and worked very nicely. Updating to 7.1 was the biggest mistake I have ever made.
OS: Windows 7
Geforce GTX 570 (updated driver 331.65)
Works fine on mine. Makes an .m2v file.
CC 7.1 Windows 7 GTX 580M Driver 306.23
Vinay has sent me the link to roll back the version. That along with the other issues I've had with 7.1 means that I won't be heading back on it in a hurray. I will file a bug but won't be able to troubleshoot due to the roll back.
