Maybe upscaled VHS masters? And by “not 480p” he means “not the quality 480p could be”? I dunno.
I dunno either. Pretty confusing original post. In any case, the DVD’s are 480i, as another member has confirmed.
Wait a moment - are the NTSC DVDs different from the PAL DVDs? Because I’m pretty sure my DVDs are 4:3
The DVD’s for Seasons 1-4 are 4:3, on both PAL and NTSC.
