I am using this Player for three days. MPD8505CP (no suffix),
Batteries ? It comes with Car Plug. Costco sell AA Alkaline for 22cents a piece. BJ club sells Panasonic NiMH 6AA, 2 AAA, and a charger for $25-$5 rebate =$20.
With such prices - 4hours? ? 6hours? Who cares?
ESP ? The manual states that while playing regular AudioCD you have a choice of ESP on or off, and the display shows it. When playing mp3 it defaults to ESP no choice.
I Compiled a mix of mp3, about 90 files 500MB, (a mixture of Pavaroti, Mendelssohn, and Pop) all files 44K 16-bit audio, mp3 encoded 128K bitrate, and normalized. No directories, all files in one folder.
I burned it on an old crappy CDRW (Hi-Val when they cost $10 a piece), using Plextor 12/10/32. The CDRW played with no problems on my computer Toshiba CDROM. On the Memorex, it was skipping 30% of the tracks, but what ever it played it played well.
I burned the exact same arrangement, and setting on a regular Maxell CD.
The Memorex performed perfectly with the Maxell CDROM, no skipping, and no noise.
The root directory contained, and played all the 90 files (more then the traditional 70).
I have a very expensive Sony portable CD-ROM. What makes the Memorex look crappy is the quality of the Plastic. The Sony looks more shinny, and metallic like, the Memorex looks like an old Radio Shack TRS-80. I don?t know about the quality of the Laser mechanism, and the electronic circuitry, which is what really counts. I really don?t care weather the plastic pigments look different then a Sony that costs more, and does not play mp3.
To use the ?Go to File? system is very cumbersome, however none of the other players have a better system.
So, all in all for the time being I am pleased with my choice.
