I have a new 240hz 46 inch led tv. and hooked a hd video converter from the 4dtv box which is 480, and jumped it to 1080 with an hdmi cable. it helped. svideo to hdmi.
Hopefully you don't mean the HDD 200 high definition decoder... cause I think just taking the Svideo from the 922 directly to the Tv looked way better... Although All HD TV's seem to handle SD sources differently ...
