Featuring a 7 inch screen, the Sony DVPFX770 portable DVD player is a fine example of just how much more comfortable it is watching this than a mobile phone screen when on the train, plane or just sitting around. Its high contrast ratio & brightness also makes it easier to see in difficult lighting conditions. In addition to standard DVDs, the Sony DVP-FX770 plays a wide variety of other discs. Xvid discs can be handled, as can most blank media including DVD+R Dual Layer. In addition you can also playback CDs in many formats, including MP3, making this ideal for both music & films on the move.
