Download Zoom Player v4.51 final.
Here is the change list from v4.51 RC1:
* New Search function on the Play History dialog. * New H263 Customized Media Playback video profile. * New AMR Customized Media Playback audio profile. * With the two changes above, you can now play 3GP files over DirectShow. Currently, this requires the use of the Haali Media Splitter with the MP4 setting checked during installation and FFDShow with AMR enabled for the Audio Decoder and H263 enabled for the Video Decoder. * New Communication API #2600 Message, allowing you to set the Derived Aspect ratio of the currently playing video. + The setting that controls whether the Increase/Decrease Rate function uses Fast Forward/Rewind or Fast Play/Slow Motion will not effect the Increase Rate/Decrease Rate functions and not only the user interface control. + The Customized Media Playback profile for MP4 files will now support the 3GP file format (which is basically the same file format). + Zoom Player no longer defaults to using the QuickTime Active-X control for the playback of 3GP files (video format used mainly on cell phones) as there is a DirectShow alternative which is much more reliable. + The "exSetMode" function can now be used to discretely set Zoom Player to Audio Mode (instead of the usual function which is an ON/OFF toggle). + Added a few safety checks so that badly formatted Communication API messages won't cause Zoom Player to crash. + Erasing a file through the navigator interfaces should no longer erase all the files with the same base name. - Color control changes should work better when the color changes are done while paused in Media Mode. - It should now be impossible for the Control Bar to appear if the internal screen saver is visible. - Manual DVD Graph mode would keep prompting you to set the DVD decoders if Customzied DVD Graph mode did not have decoder entries selected.
