I uploaded it the very same way I have all my others and when played on YouTube, it has flashes of blocks appearing in the video. When I play the produced file using Microsoft Media Player, none of that is present; it's just exactly what it should be.
So, I uploaded a previously uploaded video that runs on YouTube with no problems. I did not re-produce the video, I used the same M2TS file I uploaded the first time. Guess what - it has the problem too. The original upload, about a week or so ago still plays fine. But the latest upload of the very same file has the problems in it.
This sounds like a YouTube issue, but just curious if anybody else has experienced this or knows what to do about it????
