My sony DVP-NS500V is a dvd/vcd/cd combo player. Every time i try to play a vcd in it, it either refuses the disc and says "DISC DIRTY", or says "NO DISC". Now this is confusing because these exact same vcd's work on a majority of other players. With one exception one disc, using the exact same settings and procedure to create it does work???? I rip the sound with virtualdub, encode with tmpgenc, and have tried burning with both nero and virtualdub. Both of which yield no results. This is a pain in my side since i can no longer return the player, and bought it mostly to watch my vcd's. Can anybody give any feedback?? Somebody who might have the same player or solutions to the problem???? Thanks in advance.
