Use perfect quality (i.e. ISO's)?
Note, also, that /many/ DVD's of originally-interlaced are produced very
cheaply. In some cases, the content is "up-converted" to 480p, but the
DVD producer fails to deinterlace the content, so you get the garbage
you're seeing. I've seen this in at least one place on pretty much
every single TV-series DVD I've ever watched (often in menus or
logos/ads or credits/cut-scenes or extras, but I actually have some
DVD's where it's the entire DVD). So, make sure that the original DVD
actually plays right, too.
Just proves the old adage, "If you want it done right..." Hard to do it
yourself, though, if they sell you garbage for the source material.
