one more note, ( a chinese guy gave me a dvd and suggested me to play it only in laptop, usaile bhaneko hai, i dont know how true it is) if its an original movie (this is not applicable to unencrypted and data dvds alike) and u r using just the hardware "standalone dvd player", there is some kind of zonal division of the world as to which disks are "playable". in canada (must be in the US, for sure) it is labeled "1" and for china it is "6" arey, a chinese friend told me. dunno for nepal though, should be same as we are so much in the influence of khasa bazaar. this number is clearly printed in the cover in original movies. In laptops, they ship with universal player hardware that play in all of these zones. my guess... in branded desktop computers like dell and hp, in some machines, they might have needed the zonal thing...this part just a speculation hai.
