Motorola Dual Tuner HD DVR by Comcast - BOX FREEZING issue

by cromanorn / November 11, 2008 2:50 AM PST

I originally set out to find the answer to this problem but i was able to locate the answer somewhere else. But for those having the the issue where the box, after being on the same channel for a couple hours, completely locks up. Remote doesn't work and the buttons on the face of the box do not work either. And the only way to unfreeze is by unplugging the box. So, i went thru 4 boxes from comcast and had a tech out to my house for a few hrs trying to solve the issue. They couldn't figure it out at all. The problem has to do with there HDMI connection when being passed thru a receiver. Once I changed my thru-put to the component cables the issues stopped. Apparently the Motorola boxes see the receiver as an unidentified device when connected via HDMI and the boxes can't handle it for some odd reason. My other HD DVR is connected to my plasma via HDMI but is directly connected to the TV and that has never frozen. so for anyone having this problem try the component cables for pass thru or direct connect HDMI to your TV and see if that helps b/c apparently comcast doesn't know its own equipment and will have you swapping boxes til you die. Hope this helps someone.

Yes, its a very common issue.

This is because many cable boxes do not have HDCP repeaters implemented.

Silly. But, the only thing you miss out on is convenience. nothing else.

And besides, by having a direct connection, you benefit from getting to calibrate video per source input.

Same problem

I have the same problem with my comcast HD dvr box, its the Motorola DCX3400. It would freeze and I couldnt do anything besides unplug it to get it working again. Mine would freeze before I had the HDMI connected and I was just running off the coax. Its somthing else, I had problems before using HD. May have something to do with the signal coming in to the box.

May be a firmware upgrade for that

I probably swapped out my Comcast Moto box six times. Ocassionally a firmware upgrade will fix such problems, but YMMV.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
