The problem with the PVR-250 is, that it doesn't deliver a working transport 
stream. That's the reason why the analogtv plugin uses the PES stream type 
and converts the data stream into a transport stream internally. For 
recording this works quite well. But for live viewing there a picture 
distortions for about 30 seconds after switching to a channel provided by the 
analogtv plugin. 
I have done some experiments using the sky plugin and the pes2ts tool from 
libdvb. I changed the /dev/video2 to /tmp/FIFO in the sky plugin and used 
"pes2ts /dev/video0 > /tmp/FIFO" to convert the pes stream to a transport 
stream. With this configuration I get a stable picture directly after 
switching to the channel provided by the sky plugin.
