1. As your funds are limited, I would strongly suggest you getting the Panasonic DB35 at about £160.00. Picture quality is identical to the DB60 (I have tested the DB35 against a DB80 and found no difference in picture quality - the picture processing technology is the same)
2. Your current system will not support HD Audio. Do you have an optical output? Even if you do, you will still only hear Dolby D, and nothing more. I had a similar problem with my previous system, a Pioneer DCS363 - no choice but to sell it as it had no optical option even.
3. Enjoy the splendid blu-ray pictures for now - make sure you get a good HDMI cable. Save up and get a good AV receiver and speaker system.
