DivX Pro codec updated to v5.2, Dr. DivX updated to v1.1.5

DivX Pro v5.2 Version History:

New:

• 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

Changed:

• "Slowest" mode removed as the quality
  differential with "Slow" mode was insignificant, yet the performance
  differential was massive
  
• DivX Pro Adware bundle replaced by
  DivX Pro 6-month free trial

Improved:

• Smooth playback supporting multiple
  consecutive B-frames
  
• Quantizer, now using quant scale in
  video packets

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)

Fixed
(Decoder):

• A crash occurring in some rare cases
  with clips that have dimensions divisible only by 2 and use YUY2 color
  mode
  
• Black screen when decoding old buggy
  MPEG-4 clips that lack VOL header
  
• Internal flush operation with "Smooth
  playback" feature
  
• Intra inverse quantization (type 1)
  
  
• Support for generic MPEG-4 (XVID and
  3ivX)
  
• Data partitioning clip
  
• Deblocking to no longer cause solid
  blocks to appear during playback
  
• DivX decoder to always play DivX video

• High Definition transport stream
  encoding
  
• MP3 CBR/VBR audio encoding support
  
  
• Audio boost to fix low audio encoding
  
  
• Audio stream name detection from DVD
  input (must have IFO file)
  
• Additional 15 day trial extension
  
  
• Latest 5.2 codec
  
  
  
  • Adaptive bi-directional coding
    
    
  • MPEG-2 quantization
    
  • Bitrate calculator
    
  • Automatic updates
    

Improved:

• The DVD backup VOB analysis
  
  
• Video analysis
  
• File input analysis
  
• MP3 audio bitrate level options
  
  
• Simplicity of registration and
  activation process
  
• Accuracy of file splitting
  
  
• DV encoding to incur less dropped
  frames
  
• Accounting for RIFF chunk overhead
  resulting in more accurate file sizes
  
• Interlaced/progressive settings
  

Fixed:

• Slow audio bug for certain DV cameras
  
  
• Dropped frames when capturing to DV
  
  
• Duration analysis bug which caused
  MPEG-2 streams to be detected with shorter durations
  
• Crashes and halts which occurred when
  a third party AC3 decoder was not present
  
• A bug causing DV audio to be slowed
  when sampling rate was below 44.1 Khz
  
• The opening of transport (.ts) stream
  files
  
• Encoding for playback on PocketPC
  player
  
• A bug wherein file splitting would
  cause a crash on 2nd pass
  
• A bug that caused Dr. DivX to crash
  when using VirtualDub filters
  
• A bug wherein changing the MV path
  could cause an MV error in two pass encodes (MV is now removed from the
  codec and Dr. DivX as a feature)
  
• An issue with hidden DivX and Custom
  Profile area

DivX Player Version
History: 

New:

• DivX 5.2 decoder integrated into the
  DivX Player application
  
• Localized versions for French, German
  and Japanese
  
• Support for playback of High
  Definition clips < 2GB in file size at 720p and 1080p resolutions
  (720p playback requires a minimum system of 2.4Ghz, 384 RAM, 64 MB VRAM
  or better. 1080p playback requires a minimum system of 3.0 Ghz, 512 RAM,
  128 VRAM or better. Best viewing is achieved with post processing levels
  set to a minimum.)
  
• Enhanced MPEG-4 playback support (The
  DivX Player can now play an even greater range of MPEG-4 videos using
  the DivX 5.2 decoder.)
  
• Multiple speeds for Fast Forward and
  Rewind (Clicking the Fast Forward and Rewind controls multiple times
  changes the Fast Forward and Rewind rate.)
  
• Link to the DivX Player version
  history added to the DivX Player main menu
  
• Link to check for DivX Player updates
  added to the start menu and the DivX Player main menu
  
• Administrative access added as a
  requirement to DivX Player minimum system requirements
  
• 16-bit color depth and 64 thousand
  colors added as requirements to the DivX Player minimum player
  requirements

Improved:

• Smoothness during playback and reduced
  drive activity of files stored on CDs and DVDs
  
• The automatic check for updates
  feature (You will be prompted when new updates are available and have
  the option of installing those updates.)

• A bug that caused errors when opening
  a file from a network location by double-clicking on that file
  
  
• A bug disabling the "Cancel"
  button when opening a new movie in fullscreen mode, only allowing the
