Hey guys:

I just hooked up a second HD box in my house, Cisco Explorer 4642HD.

I was having all kinds of trouble with it, getting the "Channel is not available try again later" message. That issue has been taken care of, but I now have a different problem.

Certain channels are pixelated, some minor and some unwatchable. Some examples:

Global Toronto, CTV Toronto, Omni 2, Showcase, A&E, HGTV, TLC, Discovery, the Score, Comedy, Food.

It is on both the analog channel and the digital channel in every case. As an example Comedy - channel 50 and 285. Roughly 24 stations are affected.

I know the signal for the above stations is coming in weak because when I check the QAM stats, the level is between -10 and -12 dBmv and the S/N is between 29 and 32dB.

There is a splitter involved, and I took the splitter out of the equasion and still got the same results.

The other digital HD box is unaffected.

I'm going to call Rogers tomorrow. Any idea why only those 24 stations are affected?

Swap the two cable boxes and see if the problem persists. This will at least tell you if it's a STB or line problem.

Odd.

The old HD box in the basement has the exact same dB levels as the new one and there is no pixelation at all on the old one.

Different boxes can require different signal strengths. Call Rogers and have them check the signal to your home, put in appropriate splitters and perhaps even an amp if necessary. Your SS & SN are way too low.

Certain stations at the higher frequencies are affected first - often by an inappropriate splitter, which should be rated 5-1000MHz, bidirectional at a minimum. CBC-HD is often one of the first to go.

Thanks for the replys.

57:

The splitter i'm using is 5 - 1000Mhz. Do you think a 5- 2300Mhz would make a difference?

CBC-HD is fine. -5dbmv, S/N 35dB.

Suggest you call Rogers with that weak signal on the other channels. Unless there's something broken on the other splitter, it likely won't make a diffference since you already tried removing it.... Could be bad cables/connections somewhere.
