So Beta patch v1916 has a locked thread preventing testers from replying to it with test reports. Seems pretty silly to have a beta release and then not engage the community on the test results fellas

Anyway I have a bug to report. Many people running large widescreen HDTVS in 4K will be running a non windows default dot per inch size so the text display is not silly small on the screen. In fact on large widescreen 4K TV's, Microsoft recommends a font scaling size of 300% over windows default.

The problem is that subtitles from say MKV container movies wont display correctly - they are literraly huge when rendered on the screen. No amount of changing the front or the font size will actually fix this either. So Im running 2160P resolution at 60 HZ over HDMI 2 on my Nvidia GTX 960. Its soo large that often all the subtitles wont display because theres no space on the screen to show it all.

Also when in bluray playback, the subtitles are not as large but again there it doesnt seem that any of the user settings are obeyed with font size, font type etcetc

The second bug report is that on initial playback of say a MKV container video with H.264 encoded film, initially the screen wont display at 4K resolution and just shows a small box of video. Then after some seconds it "comes good" and fills the whole screen. The way this initialization is happening looks amatuerish and I think it should cache itself all up and only then start displaying rather than displaying wrong pictures initially.

Hi Hicham,

Thanks for getting back to me. I'm pleased to be participating in the beta test.

My test config: Windows 10 x64 (WDDM 2.0 Directx12 feature level 12.1 and downwards), NVIDIA Geforce GTX 960 through HDMI 2.0 3840x2160@60Hz. This is a HTPC configuration with a 65" UHD 4K curved LED display as the monitor. In these setups Microsoft recommend a high DPI setting with the font scaling set to 300%, and Im running 300% as the default MS recommended config. Im running Cyberlink Powerdvd ultra with the beta patch.

Please refer to these screenshots:

c15a shows some aspects of my setup

c15b shows the bug where on initial playback the video is only shown in a small box despite it being set to maximised window and full screen. As reported after a few seconds it will initialise properly and come good with fullscreen showing. The test video is just a MKV container with the usual H.264 encoded video.

c15c shows the problem of ridiculously huge subtitle fonts. Again this is a MKV container with H.264 encoded video. No amount of changing the front size desired in the cyberlink font setting menu ever changes the actual font size display. On a 65" display sitting back two meters in a usual HTPC setup the fonts are way too big.

c15d shows the font settings for subtitles in cyberlink where even trying a font size as small as 1 results in the above screenshot problem. No amount of changing the font size actually does anything in playback

With what happens in bluray disc playback as opposed to MKV playback. Here the font problem with subtitles is not as bad, but its still bad and again user settings for font sized dont seem to be actually enforced by the video player. I cant provide a screenshot cos cberlink says the snapshot feature isnt supported in bluray disc playback.

The other thing to report, and I dont know if this is supposed to be a feature of Cyberlink Powerdvd v15, is that there is no GPU acceleration being done for 10 bit video playback. This is very important for HEVC playback and when UHD 4K HD blurays start being released soon it will all be 4K 10 bit HEVC. My GTX 960 supports full hardware decoding of this and Cyberlink is lacking in supporting it.

Also I find that overtime, say 10-20 minutes into playing back say a H.264 1080P MKV file if I enable subtitle rendering cyberlink powerdvd will always crash. It wont crash right away, but it will always eventually crash. The key is having subtitles enabled. Ive sent reports of the crash via the cyberlink powerdvd crash reporter to you at Cyberlink. In the meantime if I must see subtitles Im forced into using the freeware players media player classic htpc if I want to watch a whole video without being interrupted by it crashing under powerdvd beta.

Thanks
