I prefer download MKV movies than buying BD's ...BD's totally out of my budget...just get a rapidshare and hotfile account (will cost you about rm65 per month) and can download as much as you want ... also there is torrent where u can download for free but will take days to finish download big files.... Just get a Media Player to play your MKV files...if you want better sound quality there are lots of surround sound setings in AVR's ...just choose the 1 u like ...may be its not 100% good as DTS HD or D.D True HD....but still can get better surround sound if u have onkyo or denon avr with quality speakers and woofers..

Or you can go for a DVD's (dont buy dvd's fr the guys selling at the mamak stalls or pasar malam) ...... i have about 300 movies in dvds and almost all of them are very good quality and can decode 5.1 DTS and 5.1 D.Digital...and it cost me about rm8-6 per DVD. Now days there are double layer dvd's too, which is compress version of BD's and the quality and price is also not that bad.
