#1122: Upgrade from SVN 8695 -> 8725 breaks LiveTV [DVB / XVMC-VLD]

-------------------------+--------------------------------------------------
 I've just upgraded both frontend (diskless EPIA M10k, Gentoo, 2.6.7) and
 backend from 8695 to SVN 8725.

 Pre-recorded TV plays fine (recordings made before and after upgrade) but
 LiveTV fails. Here's the frontend log on entering LiveTV.

                         You may wish to verify that your DISPLAY
                         environment variable does not use an external
                         network connection.

 At this point the frontend dies.

 For comparison, here's the log for the successful playback of a pre-
 recorded show. I assume that xvmc-vld is being used here, judging by the
 video codec.
