Having recently updated to XBMC Gotham i have found some interesting issues, such as;
- screen keeps changing size during watching videos which messes up the GUI and overscans too far
- location of some settings that used to be under system settings have gone.
To clear this up i eventually worked out where these can be fixed.
Screen changing size randomly
Most web sites tall about seeing the overscan in the system settings, which works until one of your videos changes the resolution and then your overscan is to far and the video beyond the screen. Many others refer to setting the resolution through xorg.conf, which on Gotham does not exist by default and does not need to.
You should be able to set the resolution to the highest possible for your hdmi tv, and it may be that xbmc shows a narrow view of the GUI add though it is wide screen. Also if the video chances size during viewing and then the GUI is too big after the video finishes then it's probably not XBMC as i find out, but your tv.
My tv had an auto size which could choose 16:9, 4:3 and so on. By changing this to 16:9 the screen stored changing resolution, so check your TV for aspect ratio setting.
Black lines
The black lines and videos having different assist us note dealt with by playing a video and then pressing your remote OK button.
Select the video reel icon, and this pants various video options. Here at your aspect ratio and remove black lines, and other settings until your videos look good, then toward the end of the list you'll find "set as default", which will apply it to all your videos.
You can also use the same technique for audio to boost the volume, by selecting the speaker icon next to the movie reel.
Now i can enjoy my videos without the screen keep changing. So watch for conflict between tv and XBMC aspect ratio.
