Modify firmware and GUI on a usb mp4 player

I have an universal USB Mp4 DVD board whose model is SUOER and uses chipset ZR36966. I also have the firmware upgrade disc with the firmware file. I intend to use the board to play exclusively videos in a folder. I would like to modify some functionalities in the firmware: 1. When I input a video number example 32 . It displays the video number on the screen(OSD) and then the video corresponding to that number automatically starts playing. I would like to modify this, such that when I input the video number, it does not automatically start playing unless I press the enter button. 2. When I input a video number example 32 . It displays the video number on the screen (OSD). I would like to add a field on the OSD for the corresponding video name. So that if video number 32 is Thriller, then it will display: Number: 32 Title : THRILLER I think this will require an additional file in the Video folder with the video numbers and the corresponding video names 3. I would like to be able to PROGRAM the videos to play. For Example, to play Video Number 1, then 5, then 13, then 23, then 45, ........etc I would like to be able to select and cue videos to play. Example: While Video 1 is playing , I can press number 5 and then press program button to Cue it to play next. I can also press number 13 and then press program to cue it to play after number 5. I can also press number 23 and then program button to cue it to play after number 13 ..........etc Then, when I press the program button, it displays (OSD) the video numbers that have been cued. 4. The GUI graphics in the OSD are dull. Is it possible to improve the graphics to look sleek. I have attached the firmware.
