i all, i have digital cable (not HD) and an analog hauppauge tv tuner in my windows media center (wintv-150, i believe). i'd like to upgrade to a digital tv tuner (hauppauge hvr-1600), but my question is, will i really see a substantial increase in quality? i recently got an LCD tv and noticed the poor quality of tv going through my HTPC. when i plugged the cable directly into the tv, the quality was vastly improved. will a digital tv tuner really make that much of a difference? p.s. either way, i'm going through a cable set-top box (not HD). thanks! p.s. i know it's a bit weird to post windows questions on a mac forum, but i've always had really great answers from macrumors users and i don't know of another good tech forum!
