Philips 724AT: does it play DVD-R discs?

[VEFF]

I am not too happy that my new Panasonic CP67 DVD changer does NOT appear to play DVD+R discs.

I am considering returning it and getting a Philips 724AT instead (which is only a single disc player), so I can hopefully play both DVD+R AND DVD-R.

Does anyone know if the 724AT plays DVD-R?
I have read about +R from several people...

What is the difference between the 724 and the 724AT?
Is it the Sage Faroujda deinterlacer in the latter?

Thanks for any feedback!

Got the Sony 715P. No looking back
Plays everything I have thrown at it (except MP3 DVDs):
DVD-R
DVD+R
CD-R
VCD
SVCD

Haven't tried DVD-RW or DVD+RW yet.

Also gets very good reviews.
Lightning fast to detect and play discs.
