Hey All,
I upgraded an older setup of a Samsung DLP and Integra receiver.
We went to a Denon AVRX3300 and a Samsung UN65KS8000. The cable box that stayed in the mix was a oooold Motorola DCT6200, I believe, component and DVI out only. I left the component connections hooked up and let the receiver take care of the upconversion (maybe the issue). (blu ray and xbox - fine)
The problem that shows up is ESPN HD (and others), ch202, will play perfect, but move up to TNT, ch204, and you get sound with no picture, while the cable box overlay description works. This dropout happens on a handful of stations. They will probably move to X1 shortly, so this may be moot, but any ideas as to why?
I played around with the video conversion on the Denon with no change, forced it to 1080 and 720, no difference. HDMI out from the Denon is Metra, no baluns. I thought that would rule out any possible clock stretching, but I dunno...

Probably DHCP issues with that old DCT6200 (what a POS box that was). I wouldn't worry about it, unless you have problems with the new X1 box.
But somehow, it is still the Samsung's fault :)

I can't believe I'm going to say it but, "the new X1 box should take of the problem" LOLZ :)

On demand work? Could be SDV channels not coming in. Sounds like an RF signal issue. Pull up diagnostics while on that channel if you know how.

Didn't Comcast send out notices that addressed this?
I thought that their upgrade from MPEG2 to MPEG4 would affect some HD channels when using legacy boxes.

"Well it's a cable provider issue, and their equipment. Schedule an appointment for the box to be swapped out and let me know when I can swing by during normal business hours". Back to lunch ;)

Inviting a cable guy to swap out a box when you're not there is inviting Mayhem into your life.
Remember when people here were complaining that after having a cable box installed, clients would call to say their DVD players weren't working? You'd leave a set of connecting cables for a cable box and the installer would steal the cables from the DVD player. That's the kind of mentality we're dealing with.

A good answer is easier with a clear question giving the make and model of everything.

Who said anything about the cable installer doing it herself?
Customer schedules appt, lets you know when it is within your schedule and you meet them onsite. Bill for 2-4 hours of your time. Seems simple to me.

I wouldn't even ask for Comcast to go to the home. Tell your client to go pick up a new box and give the old one back. Tell them to call you when the box is onsite. Problem solved.
