This advice is coming from a strong proponent of Windows Media Player – Ditch it! (For Video Playback at least)
I started using VLC Media Player a few months ago (thanks to Sarthak). For those who don’t know, my computer is slow with low RAM and almost all media players have difficulty playing even low-resolution videos on my computer.
VLC stands out of the crowd by allowing me and my crappy computer to enjoy full screen HD quality videos! I don’t know how VLC does it and I don’t care to find out. It is an amazing feeling to use a media player with such a light footprint and such a strong feature-set.
VLC also does an excellent job of managing codecs – I have not found the need to download a single codec ever since I installed VLC.
