Possible bug with FusionHDTV7 Dual Express

["Timothy D. Lenz" <tlenz@vorgon.com>]

For some time I have been having problems with VDR seemingly loosing 
control over one of the two tuners. It seems to be related to the 
atscepg plugin. It happened quicker after VDR had timer recorded a show. 
Removing the plugin seemed to stop it but also get no epg data. basicly, 
which ever tuner vdr was displaying from, the other tuner would seem to 
stop working. You get no signal. But only vdr needed to be restarted to 
get the tuner back. One tuner always seemed to go down within 24hrs when 
using the plugin. It seems to be related to when the plugin used a free 
tuner to scan epg.

I put a second card in, an HVR-1800 which became the 3rd dvb device 
according to vdr. Same thing kept happening. Always the first or second 
tuner since no mater which vdr was using, it would always be one of 
those that was left free. I started vdr with "-D 1 -D 2" to force vdr to 
only use 1 tuner of the dual and the second card. I also use femon to 
make sure vdr is using dvb1 after changing channels so that the plugin 
uses the second card for scanning.

It has been running for a couple of days and done recordings without 
loosing a tuner. Since forcing it to use only one tuner of the dual 
seems to have stopped the problem, it is starting to look like a driver 
problem with the fusion card. Today I used femon to put vdr on dvb2 so 
that the plugin uses the fusion to scan epg. In a couple days if the 
problem still doesn't show, I may swap slot positions of the two cards 
so vdr use the 1800 without forcing by blocking a tuner.

The plugin Author has also been looking into this, but he only recently 
got a second tuner card working.
