I recently recalibrated my Toshiba TW40x81 RPTV with Video Essentials played via a Toshiba HD-A1 through component cables. Let me tell you, HD-DVDs looked great before and now they look even better. I have a problem though. SD-DVDs, when played through either the HD-A1 or my SD Toshiba DVD player, are very dark...too dark. Has anyone else ran into this?
