Hello again. It seems there are no issues with MRV (using DECA) between the bedroom HR23-700, my son's HR23-700, and the H24. MRV'ing with the HR21-700 works fine when it is connected via ethernet, but not when using DECA, so I've concluded there is some issue specific to that DVR. It sounds crazy, even to me, but the bottom line is that ethernet works and DECA doesn't with my HR21-700. This may give me an excuse to have DirecTV replace that unit with a newer model; I was going to do that over a year ago due to a failing hard disk, but decided to plug an eSATA drive into it instead (and got much more recording time as well). Of course, I'll have to watch what's recorded on there (a "copy" feature would be useful in this case).
So the only one with an issue is the HR21-700 with an eSATA drive connected?
Have you tried...
1 - seeing if the issue occurs running off the internal drive rather than eSATA drive? (I imagine that would be a pain to do and not likely to be the problem, but it is another variable)
2 - calling Hastur for advice?
PS - Sorry... I have to admit the main reason I am making this post is so I can drop in a Cthulhu reference.
