ED plasmas have finally hit a price point where I might be interested. I have seen them on display in the stores and they look awsome,and quite close to the HDs sitting next to them. But they are being fed with an HD signal(not D*), converted to their native resolution of 480p . They also look great with 480p component attached or HDMI attached upconverter DVD players. But I watch way more DTV than DVDs. All the SD direct TV equipment only have S-video (am I correct?) . Is it even worth buying an ED plasma ? Will the ED be of benefit on an SD S-video receiver ? Would it be worth it or advisable to upgrade to HD service and HDMI attached HD receiver just for an ED ? (I have no interest in rear projection HD of any type at any price). And finally,since a direct TV HD receiver can receive all the SD channels on 101 as well as the HD stuff,(am I correct?) could I benefit from at least using an HD receiver so I can use the HDMI connection,without actually upgrading to the HD service and dish? (Can I do that?)
