| Compression/Artifacts in Washington D.C.
Hello,
Reporting from Washington D.C.....
I have a Motorola DCT3416 DVR hooked up via HDMI to a Sony 1080P LCD
AMC HD is showing "The Hunt for Red October" and it's practically unwatchable with the amount of compression/artifacts going on anytime time there is character movement on the screen or when the camera pans. Is there anyway to adjust the Cable Box to eliminate this? It makes me wonder if anyone actually watches the live feeds of the programming to see if it's up to any kind of reasonable standard.
Anyone else in DC experiencing compression/artifacts on their HD Channels? What can be done? Any help would be appreciated.

| You can try to narrow down the source.
Is it on all channels, or just that one? If it's only one channel, it's probably nothing you can do on your end. Although interference is still possible.
If it's more than a few channels, it could be other interference.
Got another cable?
Check Connections?
Turn off everything except TV and Cable Box?
Bad cables and interference aren't always easy to diagnose, but possible.
I was using HDMI with a box, and decided to switch back to Component because of the long delays caused by the Copy Protection of HDMI, and it still looked as good. Plus, if either component is older, some HDMI products didn't work well together. You didn't mention if it was working ok before, and on all channels.
SO, if you don't have a 2nd HDMI cable, you may want to try the 3 wire component cable, or the 5 wire with the audio just to check. | |

It's primarily on the "new" HD Channels, and those channels that involve a significant amount of character movement, camera movement, or action on the screen (fast movement/explosions, etc). We recently got AMC HD here in DC and the quality for some of the programming is horrendous.
I even watched Cloverfield through the Comcast HD on Demand last night and there were so many Compression Artifacts, I couldn't believe it.
I haven't tried another HDMI cable or Component. Is HDMI more susceptible to artifacts?
This is a new Comcast DVR Box and a Sony XBR5 TV

| Intermittent problems are always tough ones to figure out, but I wrote the post "Had Triple play, and happily Cancelled".
I now watch OTA HDTV and the unencrypted Free Local HD channels that Comcast is required to send by the FCC over cable that my TV's QAM Tuner picks up. I still get the problems, but I don't pay the outrageous fees now.
If your TV has a fast enough response time, probably 8 msec's or less, it's not likely your TV.
It's not likely your cable if some channels seem fine, and it only happens in "Fast" scenes.
Yes, artifacts and macro-blocks are more noticeable with digital images, so HDMI or component will pass it on.
If they are "NEW" Channels added, that probably means MORE channels, just so they can say they have more HD available than the competition. More over the same system probably means more compression of certain or all channels.
I had Comcast HD. It was awful. Beijing breaking up. I tried to watch a Musical from Cable. Jesus Christ SuperStar. AWFUL. The audio broke up every 30 seconds to one minute. It was unwatchable. So weren't some things recorded on the DVR. I called. I complained. They reset Modems and Boxes. Nothing worked.
Comcast seems to be trying to compete with FIOS and Direct TV, saying they have MORE HD. Well it's not QUALITY HD.
SO I got rid of it.
If you have a DVD with HDMI output and you can see some action movies just fine, then you know it's not your TV, or the HDMI Cable.
I use My 42" LCD HDTV as a computer monitor as well. So I can download nice 1080p Movie Trailers or free 1080p movies like "Elephants Dream". These really show the HDTV's ability. So, I KNOW my delays, artifacts and macro-blocking did not come from anywhere but Comcast. (Don't use your TV as a monitor if it's plasma).
The Source is probably good, and the Destination is probably good, it's the Company in the middle that can't deliver the goods. | |
