<div>After months of lurking around this forum, and after a several failed installations, I FINALLY have watched some HDTV via Myth! WooHoo!!!! I'm not out the woods yet, nor even close to being able to present this project to my wife, but I thought I would share some of the extra steps I had to do make it work. Hoping this might keep a few folks from having to spend hours scouring the web for answers...
</div>
<div> </div>
<div>My dedicated backend setup:</div>
<div> </div>
<div>Tyan S2466N </div>
<div>Dual AMD 1600's</div>
<div>512 MB RAM</div>
<div>Nvidia FX-5200</div>
<div>(2x) 160GB Western Digital IDE (RAID 1 - software)</div>
<div>3ware 9508-SMI 8 port SATA RAID card</div>
<div>(4x) 200GB Western Digital SATA (580GB RAID 5 - hardware) </div>
<div>NEC DVD burner</div>
<div>Intel Pro 1000XT PCI-X NIC</div>
<div>(2x) pcHDTV HD-3000 (connected to UHF antenna)</div>
<div>Sounblaster Audigy 2 (not working yet, seems to be a PCI resource conflict)</div>
<div>Hauppauge PVR-500 (ivtv drivers not installed yet... too afraid of conflicts with the HD3000's!)</div>
<div> </div>
<div>I followed Jarod's awesome FC4 HowTo guide. Without that document, I would have never been able to get up and running. However, it did seem WAY too easy at section 10 for the HD-3000 setup. Here's a couple things I had to do to make it work.
</div>
<div> </div>
<div>1. When attempting to configure my capture cards in mythtvsetup, I would get "Could not open card #0" and "Permission denied" errors in the capture card settings. What I eventually figured out was that the "mythtv" user did not have permissions to access the DVB devices. I found a hint on the pcHDTV forums that suggested I edit
<strong>50-udev.rules</strong> file located in <strong>etc/udev/rules.d/</strong> . Assuming your myth username is "mythtv", add <strong>GROUP="mythtv"</strong> to the last line of the file so that the line looks like this:
</div>
<div><strong>KERNEL=="dvb*", PROGRAM=="/etc/udev/scripts/dvb.sh %k", NAME="%c", GROUP="mythtv"</strong></div>
<div>Then reboot. This should give permission to the mythtv user to access the DVB devices. You should see the card name listed with the type ATSC.</div>
<div> </div>
<div>HOWEVER, after running a "yum update" again, it removed the changes, and I had to go back in and edit the file again. Anyone else know a better fix for the above issue, or how to make my fix permanent?</div>
<div> </div>
<div>2. So, I was really excited once Myth could access my HD-3000 cards. I then proceeded through the rest of the setup steps, but once I got to the Channel Editor step, my card would never lock in any channels. It seemed to be going through the scanning process, but just would never find any. After further research, I found out that just having DVB drivers for the HD-3000 in the kernel wasn't enough to make the card work, but that it also needed firmware. So, I did a
<strong># wget</strong> <a href="http://pchdtv.com/downloads/firmware.tar.gz"><strong>http://pchdtv.com/downloads/firmware.tar.gz</strong></a> in the <strong>lib/ </strong>directory, and then a <strong>tar -xf firmware.tar.gz
</strong>to<strong> </strong>extract the three files into the <strong>lib/firmware</strong> directory. (You should probably <strong># rm firmware.tar.gz</strong> to remove the tar file from the <strong>lib/</strong> directory). Now, when you do a channel scan, it should find some!
</div>
<div> </div>
<div>Here's where my question is: Before I can do a channel scan, I am required to create a "Video Source" (Zap2it) and then assign it to my DVB cards in the "Input connections" screen. However, after doing a scan I then have duplicate channels; the ones from the scan and the one's from the Zap2It database. How do I combine the two so I don't have duplicates? Or, is it possible just to get programming info for the digital channels OTA? I'm really confused here on this...
</div>
<div> </div>
<div>3. This one is minor, but it did stump me for a few minutes so I figured I should share. When attemtpting to record content for the first time, I noticed the backend was throwing out permission errors on my <strong>
/video/recordings </strong>directory. Make sure you have created <strong>/video/recordings</strong> and <strong>/video/buffer</strong> , and then issue a <strong># chmod a+rwx /video/recordings </strong>and <strong># chmod a+rwx /video/buffer
</strong>so that MythTV can write files to the directories.</div>
<div> </div>
<div>Last question.... I really want to use my PVR-500 with the two HD-3000's. But last time I installed the ivtv drivers it broke the DVB drivers. Anyone else able to share their steps to success with the two cards?</div>
<div><br>This is fun (?)</div>
