   I had problems with a few discs specifically ( ones over 70 mins ) on my
Yamaha CD-2. The earlyer laser tracking schemes were not as thorough as the
newer models. i beleive most of the earlyer models had one beam tracking 
where as most use two now. I also had trouble with two discs that would 
skip. I found that If I put a second disc on top of the other it would then
play! Of course the problem was a combination of an outdaterd laser and a 
disc that was maybe slightly warped..... but new players would play the
discs.
