if ifts not multiregion, i pressume it can only play R3 DVDs but don't worry i'm sure u can find a lot of resources to have it opened (so to speak) to play different regions... as for the p**** DVDs, its probably copied from say, R1 or R2 DVD but then again, most of the p**** are region free... used a samsung DVDP before and had no problem playing p**** and other region DVDs...
There's a thread before sa buy and sell section about a samsung HTIB and someone posted on how to set the player to multiregion... look for the thread about samsung DVDs for sale...
hope this helps..
