Samsung DVD-N501 Nuon DVD Player
No BIOS upgrade available
I have only viewed a few DVD's on the 501 but have already experienced some frame-lockup and skipping on one DVD.  I contacted Samsung and requested the firmware upgrade mentioned in previous reviews here on this site.  The Samsung rep told me that there was no such upgrade available and that I should return the unit.<br />The unit is easy to hook up and use, although the remote is not always intuitive especially the joystick.  <br />The picture is excellent although only a basic analog RCA cable is included.  The sound volume , played through my TV, is much lower than regular TV viewing.<br />The DVD playback functions all work well and most are useful. <br />Overall, although I am pleased so far, I will need to experiment with more disks to find out if the lockup problem is a nuisance or a deal-breaker.
