We really do appreciate you opening this ticket to help improve
Mythbuntu, but it needs to be closed for a number of reasons. The
biggest one is that upstream has moved on to a new version and believes
this to be fixed. Could you please verify if this issue still exists in
the latest version?

Please do not let the closing of this ticket dissuade you from opening a
new ticket if this (or any other) problem occurs with the newer
versions.

Title:
  mythfrontend crashes on WatchTV

Status in Mythbuntu, Ubuntu derivative focused upon MythTV:
  Expired
Status in MythTV:
  New

Bug description:
  When I click on Watch TV mythfrontend quits and a popup in the top
  right of the screen says there was a segmentation fault error code 139
  and restarts mythfrontend.

  This was not the case after a clean install of Mythbuntu 11.10 before
  updating (after installing drivers for capture card described below)
  it would display tv without any sound.

  I am using a Hauppauge WinTV-HVR-950 as the capture card. I followed the instruction near the bottom of http://www.linuxtv.org/wiki/index.ph..._WinTV-HVR-950 . I used the file from here for the pl script http://www.kernel.org/doc/Documentat...ract_xc3028.pl 
  I was not able to get sox -r 48000 -w -c 2 -t ossdsp /dev/dsp1 -t ossdsp /dev/dsp command to work but the rest of it was okay
