Well, I found this very interesting, because I thought the new mythtv was more like an "accident", especially considering the trouble it causes with the generation of the initial boot image for the Md in the beta.
Anyways, I'm in the middle of setting up with the alpha-script, hopefully this works better and lets me setup my MD successfully again. By the way, does anybody know if the v4l package has been updated too? The repo I found and described in the wiki (for the nova hd s2) seems pretty interesting and is supposed to get you s2-channels...if there is something similar included already, shouldn't it be enough to just put the firmware in its proper place and reboot?
