Query: Will not read Duel Disks

I bought my model 1731, 7" Inital portable DVD player a Walmart a week ago. I started watching aome of my faverite movies on a car trip and it kept frezzing up in the middle of the disk, I soon found out from a eletronice speicalist that it has trouble reading duel disks, well thats great all the new disks today are duel layered I only had two disk that it woud read all the way threw and that was becuase it was older DVD disk and was not duel disk. I soon replaced it with a 8" 1810 Inital and it worked great. I say do not buy the 7" becuse this model has problems.
