The most disappointing FW thus far for me is 1.07 which in fact solved many things (also many undocumented fixes) but broke many very essential playback aspects at the same time. My very old Xtreamer Prodigy in fact still does a better job than Q10 Pro for pure playing my movie collection on a 1080P TV. In literally all other aspects Q10 Pro is already far better no doubt about it but that was not the main reason to buy it.
The fact that is already the best player around for new UHD 4K HDR material is very nice technically seen and makes it future proof but almost all movies available today are either originally in DVD or BD / 3D-BD format. There is some demo material around in true UHD. Existing material is often converted to AVI or MKV. All mentioned formats will stay around for decades and should play flawless.
My review gives a good and honest total overview i think. It answers most of the original questions raised by the topic owner too.

Reading this it gives the same picture. It is already an overall great player with many goodies and high potential but the real red is in the actual Media Player core functionalities. It is taking a lot of time to get these fixed.
