I HAVE spent the last 2 hours reading the forum, searching etc, but I still can't find the answer to this! I'm considering both the Tosh 220 and the Tosh 520 - but can't decide between them. Right now, I don't have component input on the TV (and won't for a long time - just bought a new set). Aside from the obvious difference (DVD-Audio, which I MAY use in the future), is there a definite noticeable difference in pic or sound quality between these 2 machines? Some feedback here would be hugely appreciated! Cheers, Mark.
