Thank you for your thoughts Lightning UK and dbminter. I'll try again, taking into account your advice.

Nope! That did not fix the problem.

I may have identified the problem - a difference between burner write speed and DVD supported write speeds. Although I do not understand how that should create a difference between replay on a DVD player wired to my TV and replay on my computer...........

I have just burned a series of VTS files (a film) from an external hard drive to a D/L DVD. When I play the 'verified' DVD on my television, there is no sound. But if I play the same DVD on my laptop, the sound (audio) is there as normal. Any advice/suggestions as to why this should be will be much appreciated. Many thanks in advance!
