sid, i had the same problem with my older kyocera(sp), 20 year old cd player. when cranking music on the 60's, and sub, cd's would sometimes skip. i took two pieces of foam. rolled them (like a joint) and put them along each side of the player; solved the problem. i haven't had any problems with a dvd player. just replaced my older panny non-progressive with a new mits progressive and it's too new to rate.
