Advertisements How do others perceive their cable's video quality is compared to 10-20 years ago? My perception is that HDTV signals are only slightly better than high quality SDTV from 20 years ago. For example I use to have a 10ft TVRO sat system in the mid 90s and got channels like HBO, Networks, and backfeeds. Those video signals were perfectly clean, as good as today's DVD video. Today I was watching Comcast HBO analog channel and it no better than a standard VHS. Lots of compression artifacts and a very soft picture. HBO HDTV channel looks pretty good, but its slightly better than the HBO standard Def signal was 15 years ago. Scan through all the major channels, most of the standard def channels look like VHS quality, and only the HD channels looked good.
