I own a lumagen HDP [isf calibrated] connected to a 50ph9. If i purchased a blue ray or hd-dvd player with HQV processing [HQV superior de-interlacing for video/film?] and let the player perform de-interlacing via the HQV chip would I get a better image if I just let the Lumagen provide the scaling of the image? Also. for SD playback would i need to get everything re-calibrated or would it be acceptable as it is?
