I too just received a SA8000 box from TW nyc 3 days ago.
I also have a Replay and have to admit, as much as i love my Replay, the problems i was having with just my digital cable boxes were unbearable.
I couldn't ever watch a VOD movie without dropout and freezes starting around 3/4 the way through. And even watching regular digital channels like CNBC had a glitch, a drop out and audio drop out every 5-10 seconds.
I had them come over, they replaced my boxes with newer ones, it worked better for a few days and then the same old problems returned.
Even though my Replay's work great, using them with digital cable made it very unpleasant.
That is until the SA8000! Oh my God, i have been so happy the last 3 days!
Ever since I hooked it up, I haven't seen a drop-put, a single glitch, a single audio drop out, nothing wrong!
I watched 3 VOD movies so far, and all without any problems.
So for me, this alone has made tv enjoyable again.
As far as reboots, haven't had one yet, but its only 3 days, but what's the difference the cable boxes use to do it all the time anyway.
I had built little gadgets to help with that, but won't need it now with this.
Hopefully even if it reboots, it will still remember to get schedule shows.
Also, the menu's are hidden, but you can customize all recording, any way you wish, just on tuesday, first run only, even a specific time only if you wish. You need to go into the list menu and select from there after the initial recording is set.
PS, Funny thing is, the regular digital box in the bedroom got better now also after installing the SA8000, either its a coincidence or the box i replaced with the sa8000 was bad and caused all my problems on my line.
