[mythtv-users] Does anyone know how to fix duff install of Avenard Resposity / NVIDIA 1.95 On Mythbuntu 9.10?

[nospam312]

I added Avenard Resposity to my new and fully setup Mythbuntu 9.10
install but I have done something wrong as it is not able to install
libvpau1?

Does anyone know how to fix from this position?  The error is E:
/var/cache/apt/archives/libvdpau1_0.3-0ubuntu3_i386.deb: trying to
overwrite '/usr/lib/libvdpau.so.1', which is also in package
nvidia-185-libvdpau 0.  I also get a broken package libmyth-0.22-0
which can't be good.  At a quick glance Myth is still working however.

I guess it might be related to

but this information is a bit late after following the setup
instructions is there anyway to recover from this situation it will be
a disaster if I have to completely reinstall and reconfigure
everything!

TIA
