[mythtv-users] Mythbuntu weekly builds and VDPAU

[James Lambert]

Worked like a charm, looks like I must have missed something during the
downgrade!

Thanks
James

> Package: *
> Pin: origin www.avenard.org
> Pin-Priority: 600
>
> The default priority is 500, so this will put everything at
> avenard.org at a higher priority. Also when I do an update with
> aptitude and it asks for confirmation (ie Yes/No/?), you can type 'v'
> and it will show the versions that will be installed so you can double
> check that it is the right packages.
