I'm NOT trying to spend YOUR $$$$$, but my Oppo BDP~105 plays EVERYTHING without a glitch......even discs other players in my arsenal can't or won't play. I swear by OPPOs and they have a five star service department, as well, with a LIVE person manning the phone.
I honestly agree with Ralph. (4ear)
I used to have that Panasonic and I sometimes had troubles with accessing certain parts of discs, most notably, the hi-rez portion of DVD-Audios. Once I went OPPO, that all changed. Doesn't have to be the 105. Other models equally handle the various layers of discs.
