Title: mythcommflag crashed with SIGSEGV in ff_h264_pred_direct_motion() Status in Mythbuntu, Ubuntu derivative focused upon MythTV: New 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.
