I found my question on the forum and I'm having the same problem too, this is very frustrating. Once in a While it's necessary to use HDV footage (i wish i didn't have to, but...) "When playing the HDV footage, it freezes in the preview window and in the sequence too, until I hit stop it will jump to that point in the clip. If I lay just the audio clip play it plays perfectly (me too). The settings and loading is accurate to the project. Frame rate 29.97/ 1440x1080. I have imported these clips in CS6 which play flawlessly (in the past this was not a problem) but not in CC."
Please fix this problem or lets find a work around... this project is heavy based on HDV shot in 2011 - this will happen every so often - we're still going to need to get the job done.

I have no idea why your hdv clips wont play in CC.
Have you tried deleting all media cache?
When I have the symptoms you have described, I find switching to the software renderer rather than the GPU enhanced Mercury engine often fixes it.
