If your player does not have HDMI then does it have Component? If so use it. Your player isn't Blu-Ray so HDMI won't do much. Component gives an excellent picture. But if your player does 1080p upconversion, then you need HDMI. If your player is so old it only has S-Video connection, then junk it and buy a new player. I just bought a Sony BDP-360 Blu-Ray player at Costco for $99.00. It is a stellar machine. Do yourself a favor and buy a BR player since they upconvert old DVDs and the quality of BR discs will blow you away.
I have a DVD Player Pioneer DV-393 and I'm very happy with it, and I'm not thinking in change it.
But I want to update my TV for an HDTV Samsung LCD LN40C550.
So if my TV will have HDMI, how can I connect it with the DVD player that does not have HDMI and how will be the quality of the image that I play on the DVD player and display on the HDTV.
