While watching the "Raiders Of The Lost Ark" DVD tonight, I noticed two instances when the image appeared to "jump" a bit, as if perhaps a frame was missing. These occur at 15.21, after Jones and Brody have entered the hallway outside the classroom, and at 17.12 during the meeting with the fat and thin army intelligence men. My player (a Pioneer DV-563A) is still very new so I'm wondering if perhaps it's simply failing to read the disc properly. Has anyone else noticed such? Thanks to all who care to reply.
