I haven't voted yet, as it's kind of iffy. First of all, I love MRS for several reasons. Love love love! MRS is one of my favorite features after having gone from 8 years of two Series 2 units to my new Premieres.
It was going absolutely great until the recent update. I probably had one interruption in 10 programs BEFORE. Then, after the update, I started having one or more interruption (that V68 error that tells you to check a Tivo webpage that doesn't seem to exist) in EVERY program.
Now, yesterday and today, I've watched several programs using MRS without a single interruption. I wonder if that means that things have settled in. I notice, sometimes, with Tivo stuff like updates and bringing in new units, that after an initial period things settle in and work right. I'll go with that for now, but I won't be unreasonably optimistic.
That said, however, yesterday and today when I went to turn on the living room TV I was getting a 'no video signal' deal and no response from the Tivo or the TV remote. Of course, I checked to make sure the Input was on HDMI3, everything was plugged in properly, etc. Finally, on both occasions, I ended up having to unplug and restart and everything was fine.
I hope this isn't a new thing that every day, when I turn on that TV, I have to restart the Tivo. I came in kind of late and ended up missing part of a show that was coming up to record while the restart was going on. The good news was that after the Tivo restarted, it picked up the show 5 minutes in and I got the rest of it.
