Initial IDM-750DX  7-Inch Portable DVD Player with DiVX
No DL (Dual Layer) support!
This is my 3rd Initial portable player. The very first one, a 4\\", did not hold up all that well: after just a year's infrequent use (vacations) it would go for long periods of time without being able to recognize DVDs. I gave it away to my graduate student who seems to have a bit better luck with it than I did.  My second one, a 7\\", held up much better over years. My biggest gripe with it was the bad design of a battery attachment mechanism: 1 of the little plastic tabs tabs broke off and the rest bent out of shape to various degrees. It also has a cumbersome, two-piece power supply. The IDM-750DX seems to be much better designed, including the light, one-piece power supply. The main reason I bought it, however, was for the ability to play DIVX disks as I intended to dump 8-10 of them on each DVD to reduce carry-on. I was greatly disappointed when I discovered that my DL discs, that played perfectly on my Philips player, would not mount on IDM-750DX. A quick trip to videohelp.com confirmed that it indeed does not support DL, which increases the number of disks two-fold. I was disappointed, but, then again, for the price, it is a bargain portable DIVX player. If it holds up with time, I will get over my DL blues.
