After reading a bunch of very positive (highest rated at dvdhelp.com I think) user reviews on the Sony 715P (one of which compared it to the JVC 500 and Philips 724AT that I was interested in) I bought it for $120 + $7.20 tax after PM.
It is very small. Not quite as thin as the CP67 (close though), but about half as deep.
It plays all the DVD+Rs (Nero and Stomp) that the CP67 didn't, so I now know it wasn't my fault.
It even plays some old DVD-Rs burned with the old Nero that my Toshiba (which plays DVD-Rs) didn't play. I had to use Stomp for the Toshiba to play them.
The Sony is a single disc player. Not a real big deal, except for two disc VCDs and three disc SVCD videos, and it might not have the Sage Faroujda deinterlacer (not sure), BUT it is progressive scan, highly rated, SUPER quick to recognize discs and plays CD-R, CD-RW, DVD-R, DVD+R (and DVD-RW and DVD+RW; not tested by me).
Also plays both VCD and SVCD, and of course MP3 CD-Rs/CD-RWs.
It doesn't do DVD MP3 discs. I can use my PC (hooked up to my stereo) for that...
I am a very happy camper now.
I am returning the CP67 tomorrow.
