There *is* a way to make standard definition DVD playback turn into video that looks like high definition by displaying raw images without applying stupid smooth filtering.
That's rite, PowerDVD can't do that. That's rite, VLC can't do that. That's rite, MPC can't do that. Most players can't do that.
But if you can grab an old version (2003~ 2006) Elecard MPEG Player with Windows XP or Server 2003 you can view video in raw format. But his TV needs to support 1:1 pixel mapping and you need to feed the video through DVI-D connection from HTPC with descent video card. But you have to rip the DVD movie using third party software first in order for Elecard MPEG Player to play those DVD movies. Rip it to uncompressed. That's how I hit world record video quality from standard definition movies many years ago. I am famous.
