I have now solved this problem after a fashion. This was
partly due to swapping. I have now added more ram and
increased it to 6Gb so there is plenty, but the main
problem is that two of the tuners, the HVR 1700 are not
working in this release. The firmware is loading and
they get a good signal in live TV but fail to lock. They
worked brilliantly in the old mythbuntu but not in this
one. I have disabled them and I now miss no recordings
but would like to get these working again. Ideas would
be welcome.
