What is a few extra lines of interpolated resolution going to do for you? Make it look better on limited Widescreen TV's because you don't like scanlines? I for one don't mind scanlines at all. That argument is flawed.
I think you're confused about how anamorphic widescreen works for DVDs. It doesn't add any additional lines, and the DVD player doesn't convert anything. It's the monitor that does that. Most players will downconvert anamorphic to regular letterbox or zoom in, but that's just adding black space, not adding or subtracting extra lines. Like multiple people have mentioned, you give us the model number(s), and we'll take your word on these magical anamorphic-converting players. I'm with you on the whole audio conversion thing, although when it's done right by the studios (i.e. a good remix and the original soundtrack included) it can come out pretty decent. One thing you got wrong was that the original DVDs were in lossless 2-channel PCM, not compressed DD2.0. I'm not a fan of the 5.1 remixes people have done of the laserdiscs, since only the SE LDs had DD5.1, but the Definitive anamorphic's DD2.0 doesn't sound too bad. Apparently TR47's uses the original PCM, which sounds awesome. I have a clone of the Pioneer CLD-D704, the absolute best non-Elite LD player in terms of A/V quality, and my Definitive LDs sound baaaaad-ass.
ETA: Is the top pic your conversion, MeBeJedi? It looks pretty damn awesome.
