Glad it worked out. But for the record, nobody, not even Charter, broadcasts any channels in 1080p. Your TV is upconverting 480p, 720p or 1080i to 1080p. Supposedly, a new DVR interface is in the works, but it will probably be years from now, if it ever happens at all.
Incidentally, my 60/4 recently got bumped up the 64/5 which is enough to make my slingbox work a lot better.
Yes this Charter Spectrum Cable HDDVR is a beast,it only has dual tuners and a 500GB HDD,but it can do 7.1 audio if setup by the cable company to do,right now it's setup to do 5.1.
The box can output 1080p/25/30/60 or you can set the output setting to "native",right now it's setup for 1080p/60 because that's the only setting that will upconvert all the incoming signals.
The box can do a MoCA network if the cable company sets it up to do this,it's a Motorola DCX3510 and it has the iguide which is alot like the old dish guide and tivo.
Press the guide button once for the channel grid guide,or press the guide button twice for a channel list guide,setting up a favorites list is a PIA and I do not recommend it.
My Charter Spectrum Internet has been doing a faster speedtest than the 60/4 that I am paying to get lately also and it's nice to have the faster speeds for sure.
