Based on the information I see here,
http://www.solidsignal.com/pview.asp...Receivers&sku= the TV2 output is a composite base-band signal, not RF. Are you using an external modulator or the port labeled "Active Distribution"?
If your new HDTV has an HDMI input, I would recommend you use HDMI to link the sat. rx to your TV. If no HDMI, then use component (Y,Pb,Pr), S-video or composite (listed in descending order of preference). The lowest quality video + audio connection will be via RF.
If you absolutly must use RF, then you may be able to find a Jointenna at Warren Electronics.

I don't know if the VIP622 uses OTA or cable channel numbers. The frequency of OTA channel 60 is not the same as Cable channel 60.
