DVB-T crashes after 20-60 seconds

[pearless]

Hi,

I have just downloaded and installed mythbuntu RC 1, I have followed the instructions on mythtv.org to install my Hauppage Nova T 500 card and it works for anything from 10 to 60 seconds and then the mythtv front end dies. Note I selected New Zealand (where I live) and it detected all the TV channels, EPG etc.

I am using a Celeron 2.4, 512MB RAM, NVidia 5700
From "apt-cache policy mythtv-common"

I get:

mythtv-common:

and then mythtv front end disappears!

I have to start mythtvfrontend and it again works for a short period of "Watch TV" and dies again!

Any ideas?

Perhaps this is the same as Ticket #4798 ( http://www.gossamer-threads.com/lists/mythtv/commits/319345 ) ?

Cheers Douglas.

Can you try the weekly builds? http://www.mythbuntu.org/auto-builds
(Yes, it needs to say "0.21" instead of "0.20.2" ;)).

If the mirrors aren't synced yet, you can use the PPA directly: https://launchpad.net/~mythbuntu/+archive

Thanks, that helped!
