Samsung DVD-AR650 Clock Error

We've been having a timing problem with the clock on this model. It's
been staying 47 minutes off the real time. We recently had it shipped
to one of their service centers to fix the problem and wanted to get
our own DVR unit back. However, they shipped a refurbished unit and
this one has the same problem! We haven't contacted Samsung again
about the second unit but it seems to be a production line problem
with a part. Now, we bought an LG unit with comparable features. So,
hopefully it will work fine.
