hi, Just joined specifically to ask this question: Recently I bought some used DVD movies from a video game store. These had slight to slightly more scratches and smudges. They play to the menu screen OK. I'm looking for a PC application -like scandisk- I can run against these disks to determine if they will play correctly in my home DVD player (Sony DVP-S300) without having to actually watch each movie individually right away. If they won't play or they skip the store will refund. Please note: I'm not interested in ripping,copying,etc. I only want to find a scandisk sort of application to check them for playability on my DVD player. I'm not even interested in watching them on the PC-just checking them. I do have a DVD-ROM drive in my PC (WinXP-ProSP2;P4-2.53-1GB). I have tried Nero6 DVD Scandisk and Digital System CDReader 3.0 and Copy It Anyway 2.4 (in testing mode) to check for errors, but I question if these are the correct or best utilities for my purpose. Is there a specific or best application recommended to do this? Thanks.
