I have just bought an in car DVD player. I deliberately chose one that could read files via a USB port. It says on the packaging that MPEG4 files are readable. I converted several DVDs to .mp4 files using Handbrake (& the H264 codec) on a MacBook Pro. For some reason the DVD player won't recognise them. Are .mp4 not MPEG4 files? I thought they were.
Apparently Divx files are also compatible - what's a good way of turning the mp4s into Divx files please?
I should have added ffmpegX on the Mac will convert MP4 files to DIVX. But it's a bit fiddly to install due to the files it relies on having to be obtained and installed separately.
