re dvdmedia feezing and jittering

[powerimage]

am i being a good boy for not using caps
anyway...im using dvd-r media format to burn my dvds..what is exactly the difference between dvd-r / dvd+r?

when job is done on my pc i check it on my dvd stand alone player PIONEER DV350 and everything works fine ...may b cos it reads dvd-r?

two clients called and they r saying that when they r watching the dvd on their player it starts working fine in the begining but then it freezes and jitters and even stop at some points. while another client commented that dvd locks on chapter menu and wont play. pls help

Poor quality dvdr media is the problem , also burning too fast.
