I think I may have found an installation error but not sure how to correct it.<br>
<br>
I was told the HVR-2250 tuner was installed on the/at the Frontend which is why the Backend isn't able to use it (error is "tuner is not available". The HVR-1600 card is installed so the Backend can see and use it. When I'm in MCC I don't see the HVR-1600 card as being installed ==> allows me to install. When I did that the Frontend saw a usable 1600 (so at Backend) and a not available 1600 (so at Frontend). Both 1600's at adapter0/frontend0. (Everyone confused?!) For some reason both halves of the HVR-2250 card are being installed at the Frontend. <br>
<br>
Found something which sort of explains things. Using "System Profiler and Benchmark" (I installed it) under Kernel Modules I found a possible explanation of why things are wrong:<br>
<br>
Name: tda18271<br>
Description: NXP TDA18271HD analog/digital tuner driver<br>
Path: /lib/modules/3.16.0-70-generic/kernel/drivers/media/tuners/tda18271.ko<br>
<br>
Name: s5h1411<br>
Description: Samsung S5H1411 QAM-B/ATSC Demodulator driver<br>
Path: /lib/modules/3.16.0-70-generic/kernel/drivers/media/dvb-frontends/s5h1411.ko<br>
<br>
My guess is for whatever reason the Samsung driver was installed to the dvb-frontends sub-directory. The 'ko' thing is not in the tuners sub-dir. Should be easy enough to copy the file from dvb-frontends to tuners, but I have no idea how to update/correct the path.<br>
<br>
<br>
The original installation used <br>
wget <a href="http://www.steventoth.net/linux/hvr22xx/firmwares/4019072/NXP7164-2010-03-10.1.fw" target="_blank">http://www.steventoth.net/linux/hvr22xx/firmwares/4019072/NXP7164-2010-03-10.1.fw</a><br>
sudo cp -p NXP7164-2010-03-10.1.fw /lib/firmware<br>
No idea about what happened after that to place files.<br>
<br></div></blockquote><div><br></div><div>Sorry to spoil your theory, but those drivers are in the correct directories. You'll just break it if you move them. The card has a few chips that control different functions on its board (a tuner and a demodulator, in this case). So the "saa7164" driver (which is in the drivers/media/pci directory) pulls in those other two to support the other chips. The "dvb-frontends" directory has nothing to do with MythTV or the MythTV frontend. It's just the standard directory that media driver authors install their demodulator drivers to.<br></div></div></div></div>
