[QUOTE="el Filou, post: 1247011, member: 78516"] Hello, long time no see, hope everyone's doing fine. (y) I've found a bug: when aspect ratio switches from 16:9 to 4:3 during playback (like in european SDTV), the 4:3 image is not displayed in the center of the view because MP keeps instructing madVR to 'align left top'. This does not happen when starting playback directly from a position where it's already in 4:3, in this case MP does not tell madVR to align left top and the image is centered. This also does not happen in MPC-HC because it never instruct madVR to align left top even with 16:9, so if aspect ratios change during playback madVR keeps everything centered. This does not happen in MP with EVR either. Please see attached screenshots for comparison. Note that this happens only with TV channels where the stream aspect ratio changes dynamically, so I guess it means only with SDTV, or with 1440x1080 HDTV (but I think that is not used much anymore, I know it was used in France on DVB-T in the beginnings), so here's a 30 second sample to make it easier to test: [URL="https://drive.google.com/open?id=17CLRBLPQZR2mTvaX1X6wsQ4p7jXuVlJq"]MP 1.20 madVR 16-9 to 4-3 sample.ts[/URL] Tested with MP 1.20 Release, LAV Filters 0.72.0, madVR 0.92.14. It's just a minor annoyance to me because I schedule-record everything, but it forces to stop playback and restart it so for people who watch live TV it would be more annoying. Thanks a lot to the devs if you can fix it! Take care. :) [ATTACH]198229[/ATTACH] [ATTACH]198230[/ATTACH] [/QUOTE]
