Ian has been working on things so there are more fixes to come. I'll take a look at things from him tomorrow. I'm also starting to look at using this in myth so I'm sure we can get to the bottom of what is happening. Some players make some very strange decisions about the requested width. (mplayer for example seems to try to increase the width rather than reduce the height when playing a widescreen mpeg).
I'll see if I can work out why myth wants to scale to something odd like that. I wouldn't expect it to request anything bigger than the screen size so something strange is going on.
