Thanks for the update Jackal. Seems odd this is their answer as i have tested this disc on a standard slim ps3, older fat ps3 and issues persisted on both at the same spots when playing on the retail disc (disc is spotless). Go figure. I pushed through and finished the game and experienced much less of these issues in episode 4 and 5 but still a little bit of it. Great game and definitely deserved of Game of the Year, but this disc release is a very unfortunate representation of this fantastic product. Since this seems to be their response i will cease further posting about this issue and just take appropriate precautions when further purchases from telltale are made.
Again, amazing game and excellent art. Please keep making these games Telltale, but please invest more in testing on future disc releases.
