I upgraded to cs6 and... There was no dslr preset either...
You should install all the latest updates to fix the issue.
I shoot with a canon dslr 60D in 24fps and upload all my stuff in 1080p. Please advice.
Check your MOV files, they are 23.976 fps.
And again, upload your test PrPro project file along with some stills somewhere and post the links.
