Wow. I've know there were some criticisms of the R15's user manual but I just took my first look at it and was amazed at how bad it this really is. I cannot see how anyone new to DVRs would have the slightest idea how to effectively use this unit. The index alone is one page and doesn't list "Series Link" or "Prioritizer". Complete waste of trees. Oh, BTW I was looking to see what the manual stated about the options in a SL. All it does is list the options in one sentence. No description as to how they are intended to work.
