Ok, but misses the mark on one essential core function
6 of 11 found this helpful There are a lot of things I like and dislike, but overall, this DVR is really the only reasonable, 2-tuner choice for OTA watching and recording. It's a shame there isn't better competition.
First and foremost, this is a DVR, so it should excel at performing DVR functions. Unfortunately, there is one function where it fails completely.
One of the essentials for a DVR is to allow selection of extra lead-in and lag recording times beyond a broadcast show's scheduled begin and end times. This prevents missing any broadcast time slips which might include important events at the very beginning and end of a recorded show, and it also compensates for any DVR clock inaccuracies. And to be sure, we all know these slips are not rare.
If you configure for extra record minutes before (lead) and/or after (lag) show time and record a single show, the DVR faithfully honors your request and adds those minutes to your recording. However, if you set up two separate recordings at back-to-back time slots - regardless of using the same or different channels - the DVR will IGNORE YOUR SELECTED LEAD/LAG record time requests! The end result is it behaves as if you had configured for zero lead/lag times!
I don't understand why ChannelMaster chose to do this. There are two separate tuners that can operate independently (as advertised) so there's absolutely no reason for them to ignore user selected recording lead/lag times. I called ChannelMaster to find out if this was a bug and the reply I got was "that's the way it works".... not acceptable, ChannelMaster.... Epic Fail!
As for the other things I dislike about the CM-7500 design/behavior, like weird/inefficient remote button layout, odd channel guide user interface behavior, etc., I could generously classify them as just my pet peeves.
And for the things I do like, mostly I'm just happy the system doesn't freeze up and crash like my CM-7000 PAL. That, by itself, is enough to keep from returning it for a refund.
