As some of you may have noticed there have been changes slowly being implemented on TV releases. The scene has started to move to a new format away from xvid and to x264 for SD releases. Release names are very similar to their 720p HD counter parts thus a bit of confusion for users.
To accommodate the new changes the TV categories will be renamed to TV/XViD TV/SDx264 and TV/HDx264 respectively. In addition until the scene fully switches over anyone downloading SD episodes of their favorite show might have to watch both categories in order to pick up the show.
