To save me trawling through the net, can anyone give me a link to some free software I can download to convert MPEG-4 files to a file format I can put on a CD and play on my DVD player?
MPEG-4 is a video format, where CDs are used for audio files, so I'll assume that you meant 'DVD' rather than 'CD'. (There are such things as Video CDs but they're uncommon and many DVD players wouldn't recognise them anyway).
