Thanks for helping my ageing grey matter rearrange its connectors ... I was sure that I had raised this burn issue some years prior on an earlier PD spoftware but didn't know where.
Since you posted I have a solution. If I burn to a file from the Timeline I can then select the TS file and burn successfully using another supplier burning software. No distortion. Somehow the Cyberlink Burn to Disc is causing the image distortion which I solved last time with the then available Windows DVD Burner on Windows 7 ... not available on Windows 10.
Since this issue also occurred in my previous PD11 software I can only assume that there is some incompatablity. The pc I am now using is also not the same one as I used with PD 11.
When I get the opportunity I may test the Cyberlink dvd burner software again, burning from file instead of from the produced mp4 video or from the timeline.
Thanks for the memory awakening.
More searching ... I have just found this:

Maybe the stretching/shrinking is a factor of not using a Menu ... I will try to also check this out again.
