1.3 changelog:
- Using x264 r1373
- Pipes input through avs2avi rather than loading avs scripts directly. x264 and avisynth no longer share the same pool of memory.
- If a 64bit operating system is detected, the 64-bit version of x264 will be used.
- fixed an issue where it would calculate bitrate for audio, even if you weren't encoding audio.
- removed the interlaced checkbox. This option was pretty useless.
- reverted to old color scheme.
- specify a temp folder for mp4box. Should prevent errors where an output file was not created.
- fixed a bug where psy-rdo settings were disabled when using the "slow" preset.
- added support for loading image sequences. (broken, will be removed in next version)
- "keep intermediate files" option should work now
- new icon
- taskbar will light up when encoding is complete

1.22 Changelog:
- Using x264 r1251
- Medium & Slow profiles were mixed up
- Fixed an issue where audio wouldn't be recognized when your audio source was dragged onto the form.
- When generating avs scripts, it will now always use DirectShowSource. This should fix problems for people using windows movie maker.
- Modified the colors of the gui a bit so it should look better on Vista and Windows 7.
- Auto VAQ is no longer enabled by default, as there is some debate as to whether it is better.
- Fixed an issue where it would complain about the colorspace, when using FFVideoSource.
