 After some testing and discussion in IRC it appears that the xshm video
 rendering method can cause a segfault when entering the Guide in LiveTV.

 The frontend will segfault for me *every* time I enter the program guide
 with livetv if I use xshm video render method and the theme has the video
 preview width not a multiple of 8.

 If it is a multiple of 8, then there is still a problem where the preview
 image appears to have an origin of 0,0 rather than the theme defined
 location. Also the video is corrupted as shown in the attached screen
 shot.

 xlib does not segfault if the preview width is not mod8, but it does
 exhibit the same video preview origin problem.

 I am guessing this could be related to the lack of scaling support in the
 xlib and xshm video renderering methods mentioned in #4220 but I am not
 sure.
