Tvheadend

Hey there, I recently installed tvheadend. (Ubuntu 12.04, TVheadend 2.13~git20120305.0664329-ppa1~precise)

Now I wanted to install ia32-libs-multiarch, to install sopcast, but I ran into the following problem:

• $ sudo apt-get install ia32-libs-multiarch

  Abort.

Didn't really want to do that, as it seems to be an awful lot to be removed, and some of the stuff sounds important (at least to me )

  librtmp0 is already the newest version.
  Some packages could not be installed. This may mean that you have

  The following information may help to resolve the situation:

If I attempt to install librtmp0_2.4~git20120222.60218d3-ppa2~precise_amd64.deb from https://launchpad.net/~alexandr-surkov/+archive/xbmc-pvr/+build/3231485 it basically wants to remove almost all installed software in order to do so.

I don't understand what is going on there and would greatly appreciate if someone could point me in the right direction.

best,
