[mythtv-users] Installing latest xmltv/tv_grab_uk_rt in [Myth]Ubuntu 7.10?

[nospam312]

I would like to use the latest xmltv/tv_grab_uk_rt with the
timeshifted/part channel support and other new features.  Does anyone
know of the steps needed to update an existing xmltv installation to
use the new version?

Is there any instructions of getting these new features working (e.g.
how to configure) somewhere?

TIA
