Now there is! Seriously, although there are alternatives that do part of what your player does on Windows/Mac, there is nothing of the sort on Linux. Definitely make it cross-platform.
Yeah, I'd pay for something like this (for Linux) for learning Spanish. I learnt English by watching TV, and it's pretty much one of the best ways to learn a language.
A small problem is that you'd have to find enough good Spanish (as in Spain) shows/movies, but I guess there's no dearth of those.
You may try to watch dubbed Tv/Films to spanish, easier to find, and you can find the spanish subtitles http://www.subtitulos.es/ .
Oh, that's a good idea! I'll look for some dubbed movies, thank you.
How can I register more demand?
Well.. Have to say, we had it coming posting on HN ;-)
I would use it if it was available on linux !
Is there a way to get notified when a linux port is available?
think about integrating with common mediaplayer solutions, like XBMC, MythTV etc..
