Well, you don't *need* an HD capable system. I have a PS3 with a 20" Toshiba analog SDTV, and I've already stopped buying DVDs in favor of Blu-Rays. (Though to be fair, I've more or less stopped buying movies altogether in favor of converting my library-borrowed or Netflix-borrowed discs into MKVs that I can play with my Seagate FreeAgent Theater+ Media Player ... )

Point being, now that Blu-Ray players are at a decent price range, it's smarter now to buy a Blu-Ray player (which can still play SD DVD's) even if you don't have an HDTV, if only to future-proof yourself.

Besides, I'm sure you could download a BR-rip of TDK that has the shifting aspect ratio intact (some people crop it all to 2.39:1, though I don't know why) and convert that to DVD format.
