SMPlayer intends to be a complete front-end for MPlayer (video player), from basic features like playing videos, DVDs, and VCDs to more advanced features like support for MPlayer filters and more.
The version I decided to test in this review is 0.6.1 from SVN. SMPlayer basically plays anything video or audio, including DVDs, VCDs or DVD ISO images, audio CDs, MPEG, AVI or ASF. You can also play mounted images of DVDs by pointing to the directory which contains the VIDEO_TS and AUDIO_TS directories. It can also play videos from a given URL location.
SMPlayer is a fully featured video player built using the Qt 4 libraries. It basically plays anything, including DVDs and ISO images, but it skipped the menus when reading DVD ISOs. It's complete and it offers plenty configuration options, including for subtitles and the interface itself, allowing to choose the icon set and the style used. You can also configure the language SMPlayer uses for its interface, including English, Romanian, Polish, German and many other. I was impressed to see translations are pretty much complete.
