Query: Worse than useless

Just my amen to the universal dismay.We bought 3 R15s. They worked fine for several months, but then started to go bad. We've had every bug mentioned by previous reviewers.When our living room R15 died, we lost 93 hours of programming. We received a replacement, but that started to go bad immediately.Our bedroom R15 has now died, and we lost 54 hours of programming.DirecTV is sending us two more replacements. We have no hope that these will work, because they will have the same crappy software as the earlier machines. DirecTV should be ashamed of foisting such garbage on their customers.If you have any option to using the R15 -- even just the old receiver-VCR combination -- I suggest choosing it.
