参考日志：
DivX 5.2.1
The update application to allow update checks when system locale is not supported
The registration application to notify the user when they are already registered
Fixed (Encoder):
A long pause which occurred after opening the codec configuration dialog
A 1-pixel vertical wobble when de-interlacing source
An issue where the codec could forget its ’registered’ or ’6 month trial’ status
A glitch where Pro features were still selectable, but unusable after trial expired
The trial expired message to show every time a trials expires
DivX 5.2.0：
- Localized versions for French, German and Japanese
- Bi-directional coding using an adaptive method
- Fully adaptive multiple consecutive B-frames
- MPEG-2/H.263 quantization choice
- Built-in bitrate calculator
- Update checking tool
- Automatic update notification for the DivX encoder
- Fast mode, revamped for better performance, compression and quality
- Feedback mode which is now multithreaded, taking advantage of HyperThreaded or dual CPU for better efficiency
- 3 point GMC support in the DivX decoder
Fixed (Encoder):
- A rare issue where rate control sometimes inserted Q=31 frames in video combining low light conditions, high bitrate and specific motion patterns
- Fastest mode to respect the user-specified average bitrate (Old "Fastest" behavior can be obtained by disabling profiles and performing 1-Pass, Quality-based encoding with Q=3)
