Update: Please note that I am in no way affiliated to the mytv service, in fact I am no longer abroad and I have stopped using it! So please do not send comments or e-mails for support requests! This post is just describing how to convert recorded mytv files into divx format! Thank you!
There is an internet service ( http://www.greeklive.tv/ ), which broadcasts greek tv channels over the internet. It is a subscription service, but it is probably worth the money considering you can watch all shows of the most popular greek tv stations of the past 6 days. Anyway, I only use to watch basketball games.
This service has its own program (myTV.exe) , which has the ability to record a show. Now, the stream data is encrypted and the videos saved are not easy to transfer as they are encoded using a very unpopular codec. If you want to convert the video files saved by the application to DivX or other popular video formats, all you need to do is use the anyMP4 Media Converter.
