RCA RC5910P 5-Disc DVD Player
RCA RC5910P 5-Disc DVD/CD Changer
As the last review of the products states, I too have noticed this DVD player dropping frames (not sound) during DVD playback for no logical reason.  Also, I've noticed a white, horizontal line of static appear  totally random from time to time during DVD playback also.  Furthermore,  like other RCA video products I've owned it the past, the video cuts out  for a fraction of a second during white desolves (where the screen goes  completely white) or thunder effects, explosions, etc. during DVD playback.  I would not recommend this player for DVDs.  Sony will soon be releasing a  new 5-disc changer, the model DVP-C660D to replace its DVP-C650D.  This  player will also be priced at the $350 mark!  I'll keep my RCA DVD/CD  Changer as a CD changer only.
