MXF frame read errors and general render errors since update to CC

Question

Hi there folks,
Being a Creative Cloud member for a while now I share the benefits of immediate updates of CC products. However, I also get to deal with the downsides, it seems.
Since I updated to CC versions of the entire Adobe Collection I experienced unprecedented trouble with After Effects. I'll mention the most pertinent errors:
- I used to render short compositions to uncompressed HD Quicktime, functioning as a master render for future sorts of output for my clients or just to have optimum quality before further conversions. For some reason AE CC has been generating all sorts of video dropouts lately, especially when audio render is set to 'auto'. Furthermore I noticed that the only audio res that I can choose in case of an uncompressed QT render is 8000 Hz. This is new in AE CC, I don't understand the reason for this modification since the previous AE versions never had this limitation.
I must mention the fact that other output formats and codecs also suffer from dropouts, be it less frequently than QT uncompressed.
- Imported MXF files from my customers which I incorporate in AE compositions are also full of dropouts. Every dropout shows up as a single frame (two fields) of red or black. Premiere Pro encounters the same problem and reports the dropouts as frames with a read or decode error. I checked some older MXF files in previous AE projects that have been rendered and delivered perfectly in the past, but these old MXFs now appear to have the same issue. I tested the older and the new MXF on another PC that wasn't updated to CC versions and found no dropouts at all. Something must have changed in the updated codecs that belong to the CC version. All MXFs play fine in VLC player on all systems, so it's not the video source being faulty. Anyone recognize this?
I do get notifications of CC product updates, but is there a way to just update the codecs? Maybe there is a better codec for MXF.
Any help is truy appreciated!

Like often, it's better to wait a little until there's enough people experiencing the same problem. So everyone here: thanks for responding to my post! In the end it seems to have helped, considering the update of Adobe. I am still a little precautious, because some MXFs give no red frames at all (input side I'm talking about) and others still do, but then the strange thing is that scrubbing the MXFs forth and back a bit results in having less red frames to none at all in the end. The red frames now disappear and then re-appear on different points in time of the MXF file, whereas I always found them being bound to specific and unchanging points, especially on the first frame of a scene change for instance.
Anyway, Adobe Media Encoder is not suffering from this problem, so there is a workaround, converting the footage before using it in AE and Premiere. That's good enough for now. But the problem hasn't vanished yet. Another problem that I had with rendering uncompressed HD Quicktime videos that always generated dropouts has all of a sudden magically disappeared. Thanks Adobe. I see progress.
