Movies won't play! Why?

[StratMangler]

I've tried MKVs, AVIs... nothing will play. I have a few options in the Video section that are invisible yet the arrows to select the parameters for those options are still there.

When I double-click on a movie, nothing happens. If I right-click, select Movie Info and click Play, nothing happens.

Switched skins and still no go.

Any ideas?

Just tried a default version of XBMC (8.1) and it works. So I'm now downloading the most recent SVN (mine was a week old) and we'll see if it works.

It doesn't. Then, I installed a fresh version of 8.1 : works. I overwrite the older files with those of the new build : no go.

So strange that videos won't play unless I use a much older stock version.

this is not a Horizons problem and you are very unlikely to get any help here, but before I move this thread we need to know alot more about your setup.
Platform, debug log while trying to play etc.
