If it is a dual tuner, then normally you should see two separate tuner<br>
devices. Take a look at the kernel output for the HVR-2250 here:<br>

The crucial bits are these, where the two new adapters are registered:<br>

[ 20.699542] DVB: registering adapter 0 frontend 0 (Samsung S5H1411<br>

So for the HVR-2250, I would expect to see two adapters under the<br>
/dev/dvb directory, like these for my DVB-T adapters:<br>
<br>
root@mypvr:~# ll /dev/dvb<br>
total 0<br>
drwxr-xr-x 18 root root 360 Sep 24 17:35 ./<br>
drwxr-xr-x 22 root root 5700 Sep 24 17:36 ../<br>
drwxr-xr-x 2 root root 120 Sep 24 17:35 adapter0/<br>
drwxr-xr-x 2 root root 120 Sep 24 17:35 adapter1/<br>
<br>
Does the HVR-2255 do the same? </blockquote><div><br></div><div>Yes:</div><div><br></div><div>$ ls -alh /dev/dvb<br>total 0<br>drwxr-xr-x 4 root root 80 Sep 23 17:44 .<br>drwxr-xr-x 21 root root 3.7K Sep 25 08:22 ..<br>drwxr-xr-x 2 root root 120 Sep 23 17:44 adapter0<br>drwxr-xr-x 2 root root 120 Sep 23 17:44 adapter1<br></div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"> If so, they in MythTV you can just set<br>
up each of those devices as separate tuners and they should just work.<br>
<br>
And as well, multirec should work, so you should be able to record<br>
from all the channels on one frequency at once, using just one of the<br>
two devices. You need one tuner per frequency, not one tuner per<br>
channel.<br></blockquote><div><br></div><div>Okay.</div><div><br></div><div>Thanks!</div><div><br></div><div>-m</div></div></div>
