Which options to choose?

I just got a large screen TV (Samsung HLR-5667W), a home theater (Samsung HT_HDP40) and had my cable company (Adelphia) install a digital DVR. They installed a Motorola 6412 with firmware version 12.20.

I had been told that HDMI is the "best" way to go in terms of quality and ease of use, so I bought two HDMI cables: one to connect between the 6412 and home theater, and one to connect from the home theater to the TV. DVDs played on the home theater work fine, but the connection between the 6412 and the home theater doesn't work, as one of the devices indicates that there is a problem with content copy protection and suggests that I use the component connection instead.

A friend says this is a known issue with set top boxes and home theaters, because attempting to daisy chain HDMI devices is viewed by the set top box as a possible attempt to illegally copy shows that are copy protected, and that some manufacturers are issuing firmware updates to allow daisy chaining.

Does anyone know if Motorola has such an update for the 6412 or is there one in progress?

Should I even bother with this? The component connection from the 6412 to the TV works fine, and I have an optical cable between the 6412 and the home theater so I can get 5.1 audio.

The TV and the 6412 both have FireWire connections, so that's another option.

What are the advantages and disadvantages of HDMI vs Component vs FireWire?

Thanks!

Re: Which options to choose?

I'm using the HDMI cables also.  Advantages?  One cable instead of 5.  Also set my format to 720p on the tv, dvr and dvd. Seems to have the best picture.  Make sure you set your video settings on the tv for each input.  I think someone here provided the following site for setups/tips/tricks/etc.

Re: Which options to choose?

Whether or not DVI/HDMI is better than component tends to depend on the TV. Some have poor analog circuitry, so the digital looks better. Many also have default/internal/service menu settings that offer more accurate (NTSC standard) settings through the digital connection.

  As twriter posted, chaining digital video through devices is flakey at best due to HDCP issues and media company paranoia. Since DVD is a lower resolution (upconversion means the player has to guess and create new pixels to increase the resolution), and if your TV only has one digital connection, I would use component for the DVD, and connect the cable box using digital. You may even want to ALSO connect component from the box to the TV. That way, you can switch between the two to compare.

  I would avoid Firewire for general viewing. From what I've read, it slows the box down horribly, and the graphics (guide, etc...) don't show up on it.

Re: Which options to choose?

I ran into issues with 5.1 audio when I used the HDMI for video (I'm using the optical to my receiver for the audio.)  During replay or playback of a recorded program, the audio switched to DD2.0.  Since the component looked 95% as good as the digital, I switched to that and used the HDMI for my upconverting DVD player.

Oh, and I use the firewire to capture and rip to dvds.  Whenever I use it the box gets glitchy... stops ff and rew'ing so I'd be reluctant to use it.  I'd give it a try if you have an extra cable around, doesn't hurt to see what kinda results you get.

Re: Which options to choose?

Same here.  Due to the 6412 firmware bugs in 12.18, recorded content doesn't playback in DD5.1 using HDMI.   I'm using component until the firmware is updated or I switch to another box that doesn't exhibit the problem.

Re: Which options to choose?

My connection is 6412-II box to TV. Currently I'm using DVR from 6412 to HDMI to TV.  I'm finding that the reception for analog channels with this box is much worse than the reception I get with the 2500 box I have. Motorola said I may get a better picture with component cables. Has anyone tried both ways?

I have DVI-HDMI and component between the 6412 PII box and my TV. I can tell no difference in Picture Quality between the two. Except an occasional Handshake issue on the digital connection. I have heard, but not seen, that the 6412-PIII is supposed to have better PQ on the Analog channels, but it has other trade-offs.

Dump the HDMI connection.

HDMI is not yet ready for use on the Motorola DCT series of STB.

Any idea what the "other trade-offs" are? I can swap the 6412-II for - 6412-II. Should I do it?

Give me a break, please. Of course DVI to HDMI, just a small typo.  We all make small mistakes. I think everyone knows what I meant.

I'm just trying to see if anyone can tell me if I'll get a better picture with the -III and if there are any negatives with the -III.

And I apologize yet again. Two posts with two typos. I should have someone "proof" my posts. Unfortunately a spellcheck won't pick up a logic error. hmm

I meant swapping the 6412-II for the 6412-III.

Re: Which options to choose?

Hey Guys,

I've got an Olevia 437V LCD TV hooked up to the Motorola 6412 P3 via the HDMI connection.   When I switch through some of the HD channels (mostly ESPN HD) I get a green screen.  If I power the TV off & on it always corrects the problem.  Also, I get some audio distortion (crackling) when switching between all HD channels.  I contacted Syntax-Brillian and they sent me this reply:

"This is an HDCP error. This is what will happen when the security
between the cable box and the TV have been activated. This is controlled
by the cable box so you would want to contact the cable company or the
cable box manufacturer for an update on your cable box's software.  The
only other alternative is to use the component output from the cable box
to the TV".

So, can Comcast update the firmware over the wire or will I have to get a new box?  Should I just scrap the HDMI connection & go component?  Thanks in advance for the help.

Steve

PS the 6412 is really noisey, will the latest firmware update quiet this thing down?
