But as also discussed there, you can completely correct the issue by manually switching aspect ratio to "Full Screen" for 16:9 and "Keep Original" for 4:3 SD videos. Can't we?
I know it's a bit inconvenient, but it's still just a few presses on the remote, and IMO is's still better than stuck with that old player of 2.0.4. I can report some more preferable overall PQ improvement in 2.0.6 compared to 2.0.4.
(The best resolution would be of course if HiMedia would take that effort and be success in ironing all these bugs out.)
