HELP:
I just hooked up a Samsung HL-R5067W DLP and a Samsung HT-P38 HT system to Comcast Dual Tuner Motorola cable box.

Component cable from cable box to the component video in on the TV, and the audio to the HT system.

Optical audio from Out on TV to the IN on the HT system.

When I first got the TV it was hooked up to my regular Digital cable box and all the channels showed nice and clear.
Yesterday I finally got the HD cable box and the HD channels show great, but the regular channels are now very poor, lots of pixelization, text is hard to read, watching sports is very poor because I cant make out the players as they all look fuzzy running around.

Any suggestions how why this happened when i went from the regular digital box to the HD box?
Can it be fixed?

NeoPhite,
any reason why you're not using the Motorola's DVI out to your HL-R's HDMI input? Using this connection will give you the best picture. Also, how is the video output on the Motorola STB setup? Your HL-R has a native display of 720p. I would set the STB for 720p and not 1080i.

While this is not about your video display, I'm a little unclear as why you're running the audio the way you are. From your description you are utilizing the Samsung HT receiver for audio. If so, this is what I would be doing.

If you use (and you should) the STB DVI out to your HL-R's HDMI you will need to run seperate audio cables since DVI doesn't carry audio. I would run component audio out from the STB to component audio in on the HT receiver. This would give you cable audio via your HT receiver. I would reserve the HT receiver's optical audio for the DVD player by running an optical audio out from the DVD player to the HT receiver's optical audio in.

erock1 thanks for the reply.
The only reason I am running component from the cable box to the TV & HT is because I have yet to purchase the HDMI Cable, I will have one soon and connect it from the Cable box to the TV, if that would clear up the picture quality I would be very happy.
But, somehow I am not so sure, because when it was the regular digital box with the coax cable things were clear. My 2nd night with the setup and I am seeing thats its mostly text, and the running soccer players that are annoyingly distorted.

I set the cable output to be 720p which I belive is the native rez of the TV.
I tried 480i, 480p, Strecth and OFF for the non HD setting, they are all equally poor with 480i seemingly the best of the lot.

Is there a DVD of some sort that I can use to help me set the color settings on the TV?

I expect my final setup will be like this:
HDMI from cable box to TV
Component(audio & video) from HT to TV (the dvd is part of the receive just 1 component)
Component (video) from the Xbox 360 to the TV and the two audio jacks into the HT for sound.

This will leave me with a optical audio cable to spare, where should I use it?

NeoPhite,
Normally you would connect the optical out of the DVD player to your HT receiver. Unfortunately your HT-P38's built in DVD player doesn't have an optical audio out, the receiver only has an optical audio in.

What I would do then is:
For Motorola STB & HL-R:
connect STB DVI video out to HL-R's HDMI in.
connect STB optical audio out to HT-P38 optical audio in
This takes care of your HL-R's cable video & audio using the best connections.

For HT-P38's DVD player & HL-R:
connect HT-P38's video component out to the HL-R's component video in. You can connect the component audio to the HL-R too but when a DVD movie is playing you might get an echo from audio fromm the HT-P38;'s surround speakers and the HL-R's speakers. You can always turn the HL-R's sound to zero or mute. I believe on the Hl-RXX67W series, if you mute sound you're left with a silly icon on screen.

Remember, your HT-P38 will be decoding the DVD's AC-3 5.1, etc. or DTS sound, not the HL-R.
