Premiere Pro PC timeline only plays for a few frames and then no Audio after installing Miraizon DNxHD / ProRes Codec Since installing Miraizon DNxHD / ProRes Codec I am not able to play my timeline in real-time. It gives me a few frames and then the video freezes and audio keeps playing. I changed from Performance mode to Memory mode and now it will play through, however if I stop and start a couple times. It reverts to the former behavior. Specs of my system and project below.

I have Premiere Pro CC 2014 on a Windows 8 PC i7-4930 16GB RAM. Drive structure: Win/Programs on 256GB SSD, Project/Media on 1TB SSD, Preview/DB on 5TB RAID 0 7200 Seagates.

I'm working on a shortform project, basically 5 sequences comprising 18mins of a 22min show. Two streams of prores from from a 5D,6D 2 cam shoot, and I'm putting slides, stockfootage, and titles in.

I was able to play my timelines in real-time just fine (preview format DNx 115 1080p 23.976) until installing Miraizon DNxHD / ProRes codec. I got it because the editor putting the final show/QC together is on FCP7.. anyhow after installation I notice my preview files were gone -not surprising-. If I delete my preview files I get a couple clean playbacks (after they regenerate) and then the original behavior, same if I restart PPro.

I tried running the QT installer and "repairing" that after someone suggested that the QT SDK might be the issue. No difference. Makes more sense to re-install DNxHD codec from avid probably- I'll do that next. 

Has anyone had a similar issue or Can you suggest what might be going on?
According to Miraizon support this is a peculiarity in Premiere Pro handling of ProRes that causes it to interact "very inefficiently" with the the codec. There is an update forthcoming but until then they suggested this as a work-around: 
Move the AppleProResDecoder.qtx from the /Quicktime/QTSystem/ folder to a temp folder.

I still get some inconsistencies with various files under these circumstances such as "Media Pending" messages that aren't resolved and spotty playback.
This is currently working for me: 
For editing:
Leave the AppleProResDecoder.qtx in /Quicktime/QTSystem/ and move the MProResCodec.qtx from the /Quicktime/QTComponents/ folder to a temp folder. Restart PPro.
When I'm ready to export my ProRes:
Then when I'm ready to export to ProRes, I move the MProResCodec.qtx back to the /Quicktime/QTComponents/ folder and move the AppleProResDecoder.qtx into the temp folder.
Restart PPro.
