are problems.<br>

I have run a few basic tests of playback with NVDEC, VDPAU
and Standard <br>
(ffmpeg software) decoding. Also I tested recording/LiveTV
with Ceton. <br>
All tests were successful.<br>

Anybody who is interested, please build and test it to
verify that all <br>
is well before we merge it into the main master branch.<br>

<div>I have a test system with v31 on it via PPA. It's
working fine. What else do I need to do besides building
the branch devel/ffmpeg-resync. I have built from source
before, but always starting with a working system.</div>

<p>You will need a v32-pre version (master). If you run it on v31 it
will upgrade the database to v32 and then you will not be able to
go back to v31.</p>

I got the upgrade done, but it turns out that I could not run mythbackend as a service because the official .service file assumes /usr/bin/mythbackend.
