Description
I had mythweather configured to use background updates, and I noticed the following while trying to debug some prebuffer pauses:
2007-08-19 20:50:40.058 Starting update of NDFD-18_Hour 2007-08-19 20:50:40.130 Starting update of NDFD-6_day 2007-08-19 20:50:43.373 NVP: prebuffering pause: AAAAAAAAAAAAAAAAAAAAAAAAAAAaULL 2007-08-19 20:50:44.223 NVP: prebuffering pause: AAAAAAAAAAAAAAALAULAAAAAAAAAAAA 2007-08-19 20:50:45.206 NVP: prebuffering pause: AAAaAALAAAULAAAAAAAAAAAAAAAAAAA 2007-08-19 20:50:47.373 NVP: prebuffering pause: LAAAAAAAUAAAAAAAAAAAAAAAAAAAALA 2007-08-19 20:50:47.660 /mythtv/myth.current/share/mythtv/mythweather/scripts/ndfd18.pl -u ENG -d /home/mythfe/.mythtv/MythWeather/NDFD-18_Hour +41.58,-087.54 has exited 2007-08-19 20:50:49.175 /mythtv/myth.current/share/mythtv/mythweather/scripts/ndfd.pl -u ENG -d /home/mythfe/.mythtv/MythWeather/NDFD-6_day +41.58,-087.54 has exited
The scripts kicked off to refresh the weather data caused enough of a performance hit to affect the current playback.
The attached patch changes mythweather to use 'nice' to reduce the impact of the scripts. This fixed the problem for me.

Shouldn't mythweather background updates be disabled while watching TV or a video? Doesn't make sense to steal CPU cycles especially for those with frontends with slower CPUs to be quieter and consume less power.
Background updates could lead eventually to weather be shown on the main menu as the clock has been added; therefore disabling background updates all together would be undesirable.
