Ok, let me ask this question for a third time and hope that Hugh approves!

All I would like to know is when I program the 4250HD for 480i, do I still need to program the TV as well???

Since no one else knows what this question is really about (we had some PMs) - it's about stretch modes.

After running the setup wizard for the STB (enabling 480i standard, 720P, 1080i), then you need to set the stretch modes on the TV one time for SD channels and HD channels. After that, the TV will automatically detect an incoming SD signal and use the stretch mode you set for SD signals, while also automatically using the appropriate mode for HD channels.

Here's the SA STB FAQ:

Upconverted 4:3 programming on HD channels will not be stretched (by most TVs) and I suggest not stretching it since most people will then forget to unstretch when switching to a true HD programme. There should be no burn in issues, as 4:3 upconverts will likely not represent a significant portion of your viewing.

BTW, what's the make/model of your TV?

why would you program the STB for 480i?

I posted a some what detailed guide on how i set up my 4250HD with my LCD 1080p HDTV for the perfect (imo) viewing experience.

If you want to stretch the SD channels (as the OP does), then setting up the STB for 480i will allow the TV to automatically stretch SD and leave HD alone (SD and HD stretch modes are remembered separately by the TV).

This is not possible if you only enable the HD formats as you did, but since you have an LCD, that's fine for your application.

Just as an FYI, sometimes enabling 480i will also produce a better picture quality since the STB doesn't do the conversion, but the TV does. This will depend on the STB and the TV, as discussed in the following post on upconversion:
