Dual layer DVD V.S. the player

Heres the problem. I have the Toshiba 4109X and it has (since the intro to dual layer discs) developed a problem at about the 20th track it gets lost and cant continue. I was told this was a problem with the Toshiba. So this weekend I went out and bought a new Pioneer Elite DV36. From what I have read this is a great player. I rented movies and watched them both, one played fine (Unbreakable)and the other (O' brother where art though) got caught on track 20 and wouldnt play it through. Once I moved to track 21 it played on through. At first I thought there was a disc problem but there was nothing wrong when played on my computer "elcheapo" DVD-Rom. I tried several times on both the Toshiba and the Pioneer and both react the same to the very same discs. My question is what have I gained? Am I destined to this problem? I use my player for CD and DVD and both perform very well for CD. Honestly I cant choose between the two for CD playback. The Toshiba has HDCD that the Pioneer does not. The Pioneer has random shuffle and the Toshiba does not. Has anyone else had this problem?
