Missing an episode of your favorite show is something that nobody wants to experience. It's tough when you'll be watching the next episode after missing one, because you'll be wondering what happened during the last episode that lead to the events on the current episode. That's the bad thing about watching TV series seasons, since you'll have to watch every single episode so you don't get lost in the events. Good thing that you can download videos for free and watch them on your computer so that you won't have to miss a thing.
Where you can get downloads of videos
The first and most obvious sources of new videos of episodes of your favorite shows are on the websites of the TV show producers themselves. You can watch new videos of sporting events after the match online, and these will usually be free of charge because these have been paid for by advertiser's money. But these also usually just feature the highlights of the game, like those found on sports newscasts. If you want to view the entire game, you'll have to subscribe to a premium membership or download it, which is almost never free. You'll have to look elsewhere if you want free video downloads.
Other download sources
Another source of videos if you're looking to watch for free is to go look in enthusiast forums. Fan sites for your favorite series will have episode downloads available for its members, and if they don't have it, they can guide you to where you can go download a copy for yourself. It's like a sort of mini-support group for watching a series.
You don't have to miss a single episode just because you were out during the time slot of your show. The best part of browsing through fan sites and forums is that they'll typically rate the download file's quality. That way you can see if the video's any good, and if not, then you can choose another download location.
If you can't find a video online that you can actually watch and see clearly enough to enjoy it, you can go another route and download from peer to peer networks. The way these networks work is to share files from different members or peers, and copy them onto your computer. Since they pretty much have the same files, your download program can grab individual pieces from different peers and piece them when they arrive on your PC, making the entire download process faster.
File sharing works this way, and all that you need is the download program so that you can have a piece of the action yourself and download directly from those who have copies of the show that you want to watch. Select a download that has met the approval of the other members, since with multiple copies to choose from, you'll want to select the best video which would be clearest and the audio of the highest possible quality.
Best of all, this service is free, and all that you have to give in return is that you should share the videos you download to others who want to get a copy for themselves. A little sharing goes a long way, especially when what you'll get in return is a new collection of your favorite show's episodes.
