Zillions of mp3s on DVD,but it don't play!

[Peter McL]

Oooh! I had a look at BeSweet and it's a lot of technical stuff which is several miles over my head. Nothing immediately evident about converting from 42khz to 48khz. Could some kind person tell me exactly what I should be doing here? I don't know what 42Khz v48Khz is all about! Is it relevant that my .mp3s copy fine onto CD-R, which then play in my Phillips DVD R75, but when copied onto DVD+RW, will only play back through the computer? Humble apologies for tech ignorance.
