I video interviewed a client some months ago and gave him his DVDs. They were one hour 40 mins long and played perfectly on my own PC and DVD player and he played them on his DVD several times. The editing and burning was problem free and I use either Verbatim Advanced AZO DVD-R 8x Certified (box of 50) or Imation DVD+R 8x Compatible (box of 25) discs. I also stuck a paper label on each disc. Last night I got a message from his saying that two of the discs now only play for 15 minutes and then stop. Before I get back to him I wanted to check with you if there is any difference in the quality of discs - am I buying cheap ones? - or do you think it could be to do with something he has done or something is wrong with his player? I'm trying to get a business off the ground and this is something I need to sort out before I go any further. Any thoughts would be greatly appreciated.
