Any advice on getting better picture quality on a HD ready set from cable? I just got a 55" mits HD ready TV & DVD's look steller! But the only thing we want is better picture quality on cable TV. With our Sony Wega 27" Cable was not bad but not as good as DVD, with the HD ready set cable brodcasts look kind of bad although some stations looks pretty good. Will a cable signal booster work? or will a scaler be better? I checked locally & one company offers a HD converter box but there are only 3 chanels brodcasting in HD. I was told that the standard analog brodcasts will be only slightly better if any. Not worth the extra $30 a month for the HD right now. any advice? I also looked into satalite systems but no one offers local chanels. Any help or advice is appreciated.
