Finished a VV5 project and redered it into a WMV9 file at 400x300.
When playing that file with Windows Media Player ver. 9 it displays the media but shows a purple bar at the right side at any video window size but 50 %.
That doesn't seems the problem :-(
I'd made the calculations and tried with resolutions multiple of 16.
Neither works all the resolutions which are 4:3 and multiple of 16 at the same time :-(
