I have an old Pace Sky Digibox (1.3.5 according to system information on screen). I notice Panasonic now do a sky receiver. Is there any difference in the quality of the decoded signals with an up to date receiver? Are there any other receivers other than Pace & Panasonic? Any info welcomed - reviews etc. I should have said I am feeding the RGB signal from AV1 scart into a Panny 5 using a Keene Syncblaster which sorts out the sync into V & H.
