I have found several major bugs that have arisen between version 0.6.2 and all 0.7 versions.
The issues are:
Overlays no longer work
Hardware RGB->YUV Conversion causes color distortion
Subtitles cause CPU usage to sky-rocket(seems to be because of anti-aliasing, but I can't find a place to change it)
I love the new features in 0.7.* like the hot keys, but I simply can't play movies with subtitles that will use 100% of CPU or more simply to render fonts. I think the font render problem may be due to the lack of overlays and the hardware conversion. I'm running WinXp SP1 with all the updates. I have a AMD XP3200+ with a GF3 with driver version 6.14.10.5216. I hope you can replicate this problem, and fix it. Thank you!
