VLC Media Player
A professional program that can replace all programs installed on
the system as a player because it can support up to 99% of formats.
VLC is also capable of converting different formats to each other.
Consider installing heavy software such as Cyberlink PowerDVD or
Corel WinDVD on your system to play your DVDs. While this program
takes up a relatively large amount of space on your hard drive, it
also takes up a lot of space on your system memory, which is RAM,
for playing movies. But the VLC Media Player that you download from
Soft98 is very light while it can play DVDs easily.
