in the last 18 months that i have been using a PAL SD digital tv decoder box ( on a good european PAL television), i have noticed that regularly certain specific braodcasts are of a better video quality then what i can get in my DVD movies.
my DVD player is a very good high-end dvd player, and i use a good RGB cable to connect it to my CRT tv (the same tv has the digital decoder box connected to it). the digital tv decoder is similarly connected via RGB.
i thought that DVD was "as good as it gets ", but even the couple of superbit movies i have do not match the video quality in some of these SD PAL digital broadcasts.
why is this ? why cant most/all recent DVD releases match this video quality level ?
i would expect HD recorded material, broadcast in HD , and viewed on a good HD tv to surpass DVD, but this is not the comparison here.
what makes some of these SD broadcasts of such high quality ?
i am able to record some of these good quality broadcasts on my PVR harddrive ( it directly streams it in mpeg-2 to the unit's hd, and stores about one hour of video as 2 gb). the replay quality is exactly the same high quality as the original broadcast.
some points,
- my tv is 576 PAL, but is not progressive scan
( both tv broadcasts and DVD are viewed in 576i)
- i viewed some IMAX dvd's (IMAX movies are high quality video, digitally mastered from the original 70mm film), and these are good, but still not as good.
- if i can store 1 hr of this good quality broadcast video on my PVR hard disk as 2 gb, why cant my DVD movie have the same quality for a 2.5 hr movie on a dvd disk ?
- are these higher quality digital broadcasts from from some type of higher quality video sources ? i notice they often are from the BBC (in the united kingdom) and are either documenteries, some movies, or a few specific "tv series type" programs. some american shows from the discovery channel or PBS are similar in their high quality.
i hope somebody can shine some light on this issue
