This is something I really recommend.

In fact, I know how LoMásTV.com works, as I'm working for them, reviewing Spanish/English captions.

It is all about Spanish videos, with their corresondent transcriptions. Every video has the option to click on any word and see its translation.

It includes many more features, and a newsletter you can't miss!

What really makes this site different is that you can interact with the video. I mean... you can stop it, make it go more slowly, whatever you need. And every video also includes online test, to learn more vocabulary.

If you are interested, they offer a free demo, so take a look at it and enjoy!
