I have Time Warner of NY and the same DVR box connected to my Sony HDTV.But I have the problem with component cables as well.Every time I change channels not only on powering the TV up and a different resolution channel the screen goes black for a second or so scrambles before it rights itself.Its very annoying moreever I cant even tune-up the video I get one channel right the next channel is not right.I got tired doing this I am getting TW technition out today and demanding a new box and if that wont do the trick I don t want the DVR box anymore.They are charging $ 10 more for it and its degrading the quality of my TV.As for HDMI connection they told me that some of the DVR boxes they give you have HDMI connection but are" not abled" for it.
I have a Samsung LN40A550 40" LCD TV attached to Time Warner Cable's 8300HDC DVR box via HDMI. Whenever I turn the TV off, then turn it back on, the cable box reverts from 1080i to 480p every time. I have to goto Settings/Display/OUtput Resolution on the DVR set top box, deselect 1080i, then reselect it to get 1080i back on the TV.
If I use Component Video, the resolution doesn't change each time. Component Video is very good, but HDMI is definitely better.
Is this an issue with the 8300HDC DVR or my TV? Samsung insists that it's the cable box because the TV acts as a display and does not interact with the box. This makes sense, but only if the DVR can sense and adjust to the TV power being turned on and off. I've swapped out the cable box and that didn't resolve the issue.
Any ideas on a way to fix this? The problem is resolved via a manual update on my part, so it's not the end of the world. The TV picture quality is excellent. But, I'd like to just turn the TV and start watching it.
