Cablevision stretching SD channels if you use HDMI?

I got a question. I have Cablevision and I have an SA 8300HD DVR. If I use an HDMI cable, it stretches the SD channels. If I use component it is in the proper 4:3 aspect ratio. There is no way for me to over ride the setting on the box.

There website help center says the following
Cablevision recently updated the software on its Scientific Atlanta HD cable boxes to comply with HDMI standards. As the result of the update, customers using an HDMI cable to connect their cable box and TV may notice content on standard definition channels is now auto-stretching to fit the 16:9 screen.


Is it true that to complying with HDMI standards means that it will always stretch SD channel in 4:3 aspect ratio?

I believe that you can set it up throught the menus, I have not messed with it in a while but i believe you can do streched or letter box.

You might go through the Advanced setup procedure...

Personally I have my 32 inch Sharp LCD setup for 720p and the two 480p resolutions with a SA 8300HDC STB on Time Warner at a condo we own in South Texas. That way any 480i SD broadcast is converted to 480p. After selecting your resolutions power on the STB and press the Settings button twice. You can then select Set: Picture Format to Auto DVI/HDMI or Pass Through.

Alternatively selecting Up-Convert-2 would convert HD to 720P and SD to 480p. Selecting Up-Convert-1 would convert HD to 1080i and SD to 480p.

I have a 50 inch Panasonic Plasma at home that I have setup for Fixed 1080i. That is because of the way Cox does its iTV function and HDMI handshake issues with the TV and the SA 8300HD STB.

I tried that and it still doesn't work. Actually it only lets me select Auto DVI/HDMI when I use and HDMI cable. I think Cablevision changed something. I guy I work with says he has the same problem, so I think Cablevision did something. Maybe they got too many complaints from old people that wanted it to be stretched, so they decided to auto stretch non-hd channels to get less phone calls and make them happy. As more and more channels go HD, I guess it really isn't an issue.

You are probably correct about why they did it. I hope Comcast here in the Chicago market does not do anything like this. Stretch-o-vision drives me crazy.
