To many people, probably not. Technically, however, watching one of the LD anamorphic transfers on a standard TV is the worst combination possible. The LD transfer had to be upsized to anamorphic, which causes some loss in horizontal quality (which can be minimized by, for example, interpolation.) Now, if you play this transfer on a standard TV, the DVD player must remove this extra video information - that you just got done adding - in order for the picture to fit the screen.
Rather than go through this double-resizing of the video, which can easily result in artifacts, it's best to simply watch a letterbox SW DVD on a standard TV, and an anamorphic SW DVD on a widescreen TV.
