I have a DVD-ROM in my computer several years already but only recently started to use it to play movies, because only recently DVDs became more widely available in Lithuania.
So I have a few questions about this format:
1.Does the video quality differs from DVD to DVD? I mean not the differences of screen proportions, but differences in resolution. If there are such differences, could they be found somewhere on DVD case?
2.Another question: does DVD video quality/resolution differs from VHS (TV) one? If so, could anybody tell exact numbers. Also, if movie was made for video/TV only, does that means that it's quality will be like TV one and not like DVD one?
3.DVD prices here are very varying. You can get a new (legal) DVD for as low as 20 Litas (5,7 Euros; 6,6 $ ) and others costs way over 100 Litas (30 Euros; 33,3 $ ). What causes such cost differences? Is it only the movie you are buying or also some characteristics, e.g. video quality?
4.Does video quality depends on DVD player software? Once I had downloaded a free DVD software, it was in French and thus I had hard time understanding it. The program was lost when hard drive was formatted. So now I have Leadtek WinFast DVD player. However, it seems for me that the video quality is worse when using this program, resolution is lower... Probably because now I use 2048x1536 resolution ussually, while previously I had 1600x1200 on my Windows. But still I am asking this.
5.Are DVD regions important anyhow if I am playing DVDs on my computer, not a DVD player? If so, could I "overcome" them by just changing my regional settings (e.g. write that computer is in USA or China, depending on region), downloadng a different DVD playing software (associated with other region), etc.?
Thanks in advance for answers,
