Firstly, Pardon my ignorance on these matters but I'm not much of a tech head! The thing is I'm about to buy one of the new Panny DVD players that will playback RAM discs - I have the Panny E50 recorder so I want another player to allow me to edit my recordings properly. I have a choice of two: Panasonic DVDS35 & the Panasonic DVDS75 They both have similar spec, except the S75 has the following extra features: Compatible with DVD Audio Double Digital Re-Master Hi-Mat Compatible Progressive Scan (NTSC) DVD Audio playback would be nice but I can't really see me taking advantage of it that much. Can someone explain what Double Digital Re-Master & Hi-Mat Compatible mean Mainly I'd like to know if NTSC Prog Scan would make any difference on my 100Hz Tosh 32inch Picture Frame telly? Will I get any benefit out of these features and is it worth me paying the extra £40-£50 quid for the S75, or will the S35 suffice? Thanks in advance.
