Closed-caption television may also not be possible. However, this is usually the case with TV software for PC. Even most streaming videos do not offer closed-caption services.
At the end of the day, using this type of TV software can be helpful when going after the good brands/services. With all the content at your fingertips to watch TV online, theres no need to search for anything online. This will also eliminate having to travel from one TV/VOD website to another to watch a sporting event or movie or TV show.
