1. "What do I need to convert a .mp4 file to so that it plays on an LG DVD player through USB?"
2. "My newly bought Sony DVP-SR760HP DVD Player not playing MP4 or most AVI videos connected through USB. Its giving "Unsupported format error" for MP4 videos. Can DVD player play MP4?"
Up till now, there are lots of DVD players on the market with the notable brands such as Sony, LG, Philips, Samsung, Panasonic, etc. Regardless of brands and models, most of them now support USB content playback with some certain formats. However, we will often fail to play MP4 on DVD player via USB port since seldom of the DVD Players support MP4 format (though some models support "simple MPEG-4", the codec of MP4 format varies).
For the reason above, first of all you need to check your DVD's manual for supported file format. Commonly, the video formats that a DVD player supports are MP4 (MPEG-1 & MPEG-2), MP4 (H.264) or DivX. If your media files are not supported then you need to convert them to the compatible formats. To do the job, you need to get help from a professional MP4 to DVD Player Converter for Mac (MP4 to DVD Video Converter for Windows).
Free download the MP4 to DVD Player Converter, set it up and then run the program. In the interface, click "Add Files" button to load the MP4 file into the program. Once loaded, you can click the play button to preview the content.
Like we said before, you should convert MP4 to DVD player-accepted formats, such as DivX. Hence, please hit the "Profile" button to open the format list, from which, you should choose "AVI(Divx)(*.avi)" from the "Common Video" tab or choose "HD Video"-- "HD AVI(Divx)(*.avi)" for converting HD MP4 videos.
Finally, you can hit the "Save to" button to choose a location for saving the output file. Then, click the "Start" button, the program will automatically launch the conversion. Once it is done, click "Open Folder" button to locate the converted MP4 files and you can play mp4 on dvd player freely with no worries.
