Burned a DVD, which contains 6 small (5 mins long) music videos of our band.

When I play it on my Computers Pioneer DVR 104 internal drive through WinDVD it looks and sounds great. Audio is crystal clear etc.

However, when I play it in my Commerical Panasonic A360 external drive the audio is very crackerly, and video occasionaly skips. The audio also seems to "worble" ie the sounds although not crackling seem to go out of tune.

Could this be

a) The Discs I'm using to burn with. These are currently unnamed brands etc Should I buy better quality.

b) Or could the fault be with my A360 External unit (Note: I've not had a problem with commercial DVD movies etc).

Any suggestions etc would be most appreciated.

Cheers
Andy
