Has anyone started a general area to post questions and answers about the motorola DCT 64xx boxes. I can't find one when I search. I find small threads about it all over the place but no general thread with a wealth of information.

If there is one can someone direct me to it?

If there isn't one can we start one under this post?

Hi all,

I just got a Motorola DCT 6416iii with timewarner (formerly Adelphia in Los Angeles).

I'm having problems outputing HD content downscaled to SD in widescreen enhanced mode to offload the DVR recordings when it becomes full.
I'm attempting to record output from S-video at 480i from the 1080i or 720p recordings on the DVR. The DCT is set to 16:9 output and also to 480i output.
Since the TV is set to 16:9 the output signal should be 720x480@1.2 pixel aspect ratio. Which would be the same as DVD widescreen enhanced and you'd use the fill button on your TV to make it fit perfectly.

The DCT 6416 doesn't output like this when you go to SD 480i or 480p. It changes to 4:3 aspect ratio and outputs a letterboxed signal with the black encoded in the signal. This is a HUGE loss of vertical information. My moxi box this DCT replaced output widescreen enhance perfectly. Is there any way to force this to output widescreen enhanced that someone could point me to?

I'm about to attempt to use the 1394 firewire to grab on my computer non-5c flagged recordings but I wanted a way to do this over normal cables in SD to my non-linear editor for DV grabs off the PVR, that worked for any channel beautifully with my Moxi box.


Thanks much for any information!

P.S. Here's what Motorola had to say on the subject:

DCT6416III
original question:
Is there any way to make my DCT6416III downres HD content to SD 720x480 1.2 pixel aspect ratio like a DVD uses. Widescreen enhanced using fill.

Currently when you down res HD content to SD with your box it letterboxes the content at 720x480 using .9 aspect ratio pixels. This loses LOTS of vertical resolution and is a really bad way to downscale HD contnent. Widescreen content should be shown 720x480 with a 1.2 pixel aspect ratio and you should use your fill button on your TV to fit it to the 16:9 screen. Add modern DVDs for widescreen use this mode to maximize vertical resolution.

I'm trying to burn SD DVDs of HD things that I want to delete from my DVR, but I don't want to lose this much resolution.

My Moxi box did this perfectly. I can't keep this box if this is the only way it down scales the HD.

Thanks,
-michael

Mr. Addabbo,

Thank you for choosing Motorola! I apologize about this inconvenience, but I will be happy to assist you with this.

Have you tried going into the Menu settings and changing the ratio on the box?

You can visit our web site at www.motorola.com/broadband to access your user's guide and frequently asked questions about your product. Thank you for choosing Motorola.

I replied online after logging on. It is still a problem.

Yes, the DCT is set to 16:9.

I'm going out the component cables.

I'm set to 1080i normally which works fine.

If I set to 480i for SD output of HD recordings to offload old HD to DVD for
instance I run into the problem I'm describing where it ignores the 16:9
setting and shows 4:3 letterboxed.

I'd like it to show 4:3 widescreen enhanced and use the fill button on the
DVD.

Is there a way to do this?

Thanks much,
-michael

Mr. Addabbo,

No, there is not a way to do that.

Please add that to the wish list / bug list.

I feel that's more than a wish actually.

If a user sets the tv aspect ration to 16:9 then any resolution they set the output to should send in an ideal way to the 16:9 aspect ratio.

The results are inline with a setting of 4:3 for the tv aspect ratio. Then you would expect letterboxing.

For 480P and 480i the correct 16:9 output is 720x480 at .9 pixel aspect ratio.

The user should use the fill button to correctly stretch the image to fit the screen.

Your box by outputing to 4:3 aspect ratio and letterboxing is losing TONS of available resolution for no reason. This is really a bad way to output to SD from HD. I can't understand why this was done.

The moxi box I had which I believe was made by motorolla did not do this.

Is there any possability this will be corrected in the future?

Thanks,
-michael
