last night I found 113 and 114 SRPMs on an archive site somewhere,
unpacked them, applied patches and then diffed them looking for any

I unpacked a 115, hacked its patch to undo this change, rebuilt
overnight, installed and tested this morning - result - SUCCESS :-) !
Does this imply that building w/o patching resulted in a failure, or
did you just try that one build. Perhaps it is unrelated, and only a
build w/o a patch will tell.
I don't follow...
113-5 all apply patches as part of the build. Vanilla 113 works for me,
Vanilla 114/115 don't. All I did was to find a XVMC related difference
between 113/114 and then remove that difference (from the patch that
created it) in 115, creating a variant 115 binary which worked for me.
I know that the vanilla 115 distro does not work for me.
I know that my hacked 115 distro (with a couple of lines removed from
the svn patch) does work for me.
I'm assuming that rebuilding a vanilla 115 SRPM would result in a
vanilla 115 RPM so did not bother with that build.
The difference is not only in the patches, but also in the
environment. I found out that FC's updates overwrote my libviaxvmc
lib, so the packages had no VLD support indeed.
I assume that if you simply rebuild the 115 sources you'll have
success, too.
Well, much to my chagrin, Axel, you are right :-)
I rebuilt the 115 SRPM last night and it works fine.
I think it probably comes down to the fact that the xorg that I am
running includes a unichrome backend along with the relevant C header
files, which eclipse those in the xvmc package. I guess these were
similar enough for 113 to work without a rebuild, but by 114/115 libmyth
needs rebuilding in my environment to work properly...
Anyway, a successful resolution - apologies for all the wasted bandwidth ...

Is that clearer ?

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
?
Looks to be an atrpms problem - this code is how it should be in the
release-18-fixes branch.
I think so, too. I'm looking into this, but I have no VLD hardware to
test with, so I'll be fixing things blindly. Anyway, better than it
not working at all, and I can verify that non-VLD stuff is still
working.
