Adobe Media Encoder CC Outputs Corrupted Frames

Question

The film strip below tells the story - these are 6 frames from the rendered output of a project. Frames 1 & 2 fine, frames 3 lots of blocks and pixelization, frame 4 jumps back a few seconds earlier in the clip(!), frame 5 blocks and pixelization again, and from 6 back to where we should be. (Note that the pixelization actually occurs for 2 frames either side of the "historical" frame, I've only shown one each side below to shrink the image a little - happy to upload the full sequence as images or YouTube, etc).
Has anyone else encountered this? Fixes? (HELP!)
I originally output this a couple of months ago. I just updated my CC software to the latest yesterday and tried again - output is the same. I have output with different settings (one pass, two pass, various other quality features turned on / off), always the same output. The complete output is 4:17:39:07 (yep, just over 4 hours), and the corruption starts at 2:48:59:10. Source video is clean, and if I pull just this section out to its own timeline and output, it outputs clean - that's how I ultimately fixed it (output the piece separately, hand edited it back into place with TMPG MPEG editing tools). What scares me MOST is that I only noticed this because it was right near a chapter stop on the final DVD - where else is my video likely to be corrupt?!? I don't normally watch every frame of the final rendered output (it's all reviewed during the edit), and I shouldn't have to. I'm wondering now where else this might have occurred that I don't know about.
For review, here is the summary of source / output data:
Source: Sequence, 2013_08_31_National, 1440x1080 (1.3333), 25fps, Upper, 04:17:39:07, 48000 Hz, Stereo
Output: 2013_08_31_National.m2v, PAL, 720x576, 25 fps, Lower, Quality 100, VBR, 2 Pass, Min 2.80, Target 4.10, Max 7.00 Mbps, Dolby Digital, 192kbps, 48 kHz Stereo, 16 bit
I normally have "Render at Maximum Depth" and "Use Maximum Render Quality" checked on the final output, although I did do an earlier draft output of this without those checked - exact same frames had errors.

Answer 1

I have the same problems making videos for a DVD.. I have been rendering output for 15 musical videos, and they behave like madmaxmovies explains. I don´t know how to get a film strip like above, but my videos do the same. Out of the 15 videos, only one has no problems at all, the rest have like 2 - 3 such passages in every video (2-3 mins long)
Source (example): AA040101.MXF, Type: XDCAM-HD 422 Movie, File Size: 1,9 GB, Image Size: 1920 x 1080, Frame Rate: 25,00, Source Audio Format: 48000 Hz - 16 bit - Mono, Project Audio Format: 48000 Hz - 32 bit floating point - Mono, Total Duration: 00:05:55:05, Pixel Aspect Ratio: 1,0
Output (example file): PAL, 720x576, 25 fps, Progressive, Quality 75%, VBR, 2 pass, Min 2.80, Target 5.00, Max 7.00 Mbps, PCM Audio, 48 kHz, Stereo, 16 bit
UPDATE:
I tried to make an output directly from PP. The first result was good - no problems, but in second output the problem occured again, in a different spot compared to the "Jump" in the previous output.
When importing the mpeg-file with corrupted frames, into a timeline in the project, the output of this video-file did not have any corruptions in the spot where it previous was, Also when rendering just a small part of the original file, around the spot where the corruption had occured before, this output was ok.
