Hmm. I got it and so far overall I like it. The picture quality is outstanding, with an admittedly small optimal viewing angle without degradation in picture quality. This isn't an issue if you are watching movies alone or with a loved one (my wife), but may present problems for friends with insecurities about their sexuality.
Sound quality is generally ok, with a notable weak dynamic range with the built-in speakers (which they shrunk to expand the screen from 8 inch to 8.9 inch - 1500 to 2000 model). I suppose this is to be expected to a degree, but I was still disappointed. I even tested the 1500 right next to the 2000 with a few scenes from Diehard, and there was a significant difference in speaker power, and overall texture, with the 1500 edging out the 2000. Oddly enough the 1500 is still priced $150 more than the 2000. Still, this makes no difference if you use the line out->amp->headphone route, as most of us would do anyway.
Dual headphone jacks are a nice convenience, but I ended up going with a Kimber splitter to accomodate my wife and I through the cosmic when we travel together. For $79 I expected better out of the splitter (it has a background hum and there is degradation of sound, even on my home system), but part of this may be just standard loss when any signal is split, and it gets minimal use anyway so no worries. The dual headphone line out is acceptable quality, and should be fine for most users (ER-4P and Sony V6 tested, both fine with an obvious boost to the Etys).
The quality of the line out is excellent, no complaints there, using a cosmic with ER-4P/Ss.
You can play CDs with the screen almost closed, but it *is* a design flaw that the Toshiba "screen saver" is on 24/7, wasting precious portable battery power for absolutely nothing.
The battery makes this player a heavy person, and it BARELY fits into the larger headroom traveler bag with the cosmic. I am still able to turn it into a traveling theater though without too much fiddling around. The life in the included battery is about 2 movies (3.5 hours), and I've had no problems with residual battery drain (Robbster I think your battery may be bad?) I tested this a few days ago by charging it and leaving it unused for about, oh, 30 hours, and then watched Gladiator and most of The Matrix before it kicked off from battery drain. The extended life battery is reported to last 5 hours, but the person is $179 at it's cheapest on the net, and most of the net places that have it for under $200 (msrp $250) are out of stock.
I opted to blow the extended battery off in lieu of just buying a decent pcdp to handle the music end on long trips, which btw is why I checked this forum tonight in the first place, haha. There will be some hassle bringing both the dvd player and the pcdp and the amp etc, and switching it all out, but this will only really happen on overseas flights, and I've got a backpack for those flights anyway, so no big deal. Also, if you fly business class on most airlines these days they have jacks you can use to power the portable, but I haven't personally confirmed the type of power source or what adapters may be needed (if any).
MP3's *can* be played but it's a real pain in the ass: the SD-P2000 requires a boatload of specifications - eight letter name maximum, 320 kbps, etc - it's all listed on page 32 of the manual that ships with the product. The list is long enough for me to say with authority that you should not consider using this device for MP3 playback (basically seconding Robb's statement).
BOTTOM LINE:
Pros:
* excellent video image quality
* full color and picture manipulation controls
* progressive output format ability
* sound reproduction through line out jack
* bitstream out jack (DTS)
* dual headphone jacks - acceptable sound
* unit comes with standard cables for audio line out/video out
* remote control
* zoom feature (minimal degradation of picture resolution)
* can be used as a spare home dvd player, say, in a bedroom, with line out (svideo), bitstream, and powered by wallwart.
Cons:
* a bit heavy and cumbersome; larger than most dvd portables.
* weak sound through built-in speakers
* possible battery life issues (Robbster)
* pain in the ass MP3 playback requirements
* expensive at near $800
Hope this helps.
