last night I found 113 and 114 SRPMs on an archive site somewhere, 
unpacked them, applied patches and then diffed them looking for any 
mention of XvMC - sure enough, I found one :

diff -r 113/mythtv-0.18.1/libs/libavcodec/parser.c 
114/mythtv-0.18.1/libs/libavcodec/parser.c
814c814,818
<     { CODEC_ID_MPEG1VIDEO, CODEC_ID_MPEG2VIDEO },

 >       CODEC_ID_MPEG2VIDEO_XVMC_VLD,
 >     },

I unpacked a 115, hacked its patch to undo this change, rebuilt 
overnight, installed and tested this morning - result - SUCCESS :-) !

I have probably not so much fixed a bug as disabled some code that was 
enabled in 114, but it works for me - I now have h/w accelerated MPEG2 
on libmyth-*115* so I am happy.

Thanks for the help, Axel.

Should I let someone know about this somehow, or will you feedback to them ?
