Quality Control Problems
I purchased 2 of these units 4 months ago and they worked flawlessly.  Recently though, I purchased another unit and it made an anoying high pitched wine and the picture would freeze constantly.  I returned this unit for another one assuming that I had received a rare &quot;bad&quot; unit.  The replacement came a week later and had the exact same problems with the high pitched wine and the picture kept freezing.  This has led me to believe that Norcent has some serious quality control problems.
