Toshiba makes an excellent unit. The screen display is surprisingly good. Costco has them at a very good price.
Here's a blurb about the SD-P1850
" The Toshiba SD-P1850 Portable DVD player features an 8" Widescreen, with invert display mode TFT LCD Display with 480x234 Pixel Resolution, that is great for viewing standard, letterbox and anamorphic DVDs. The SD-P1850 is DivX® Home Theater Certified and allows playback of DivX, AVI and MPEG4 (.ASF) compressed files downloaded from the internet from a personal computer and stored on a CD-R/RW. The convenient Audio/Video Input and Output provide connection to an external monitor or using the SD-P1850 screen and speakers as the display device. The built-in 4-In-1 Card Slot accepts Secure Digital, Memory Stick, XD Picture Card, and MultimediaCard. The SD-P1850 also features a JPEG Viewer that enables a user to display digital photographs on the LCD screen or a television set in the JPEG digital format."
We bought one for a relative and tested burned discs on it. Perfect. It really seems like a well-built machine.
One review on Cnet
gave it high marks.
