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:
mythcommflag crashed with SIGSEGV in ff_h264_pred_direct_motion()
Status in Mythbuntu, Ubuntu derivative focused upon MythTV:
Expired
Bug description:
mythcommflag was processing a DVB-T SD recording of "Carter Can" from
ChoiceTV in the usual New Zealand format. I have recorded many
episodes of this program before on Mythbunt 11.04 with MythTV
0.24+fixes, but I upgraded to Mythbuntu 12.04 with MythTV 0.25+fixes a
few days ago and I have only recorded one or two of "Carter Can" since
then.
