A complete new rewritten version of Dreambox ReStream is available. It is still an alpha version, but it should be pretty stable.
This version has a different code base, and has a different look. This version also supports streaming of your movies on disk like it were Dreambox recordings.
The iPhone support is still a bit buggy, but you should get a nice page when you use your iPhone / Blackberry on ReStream 2.0 website.
Download the 2.0 source code from the project page.
