You record teletext so you can listen to the music?... O....K.....

The problem you mentioned with recorded DVDs not playing on certain players is actually down to the make of blank disks you are using. Some makes of blank DVD-R won't work in all DVD drives. For example 4x speed Datawrite discs can't be played in my Sony DVD player, but every other make I've used will. These days I just stick with Verbatim DVD-Rs. They may cost a little bit more, but they work in everything I've every tried them on and are higher quality and more reliable.
