<div class="WordSection1"><p class="MsoNormal">I’m new to the HD-PVR and have recently
installed it on my working backend. It is mostly working now
– I can tune live TV using it and recordings fire off a
channel change. I’ve got a problem with my channel change
script when starting a recording (which doesn’t happen with
live TV) but I should be able to figure that out on my own.
But I also see that the HD-PVR sometimes doesn’t stop
recording. The show it tried to record (but recorded a
different program instead due to the aforementioned script
issue) lasted a half hour and MythTV seems to have correctly
stopped recording at the half hour mark even though the HD-PVR
didn’t get the notification to stop recording. <o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">To try and debug it, I thought about
looking into a script to reload the hdpvr module. Seemed
simple enough and there are script examples out there. But
when I try typing the following in the command line: <o:p></o:p></p><p class="MsoNormal"> sudo modprobe -r -v hdpvr<o:p></o:p></p><p class="MsoNormal">the command just hangs there indefinitely
showing:<o:p></o:p></p><p class="MsoNormal"> rmmod hdpvr<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal"> I can kill the sudo process that kicked
off the modprobe but I can’t kill the modprobe process. The
only way I have found to clear the problem is a reboot and
even then, during shutdown, the process won’t die and hangs
the computer on the waiting for processes to end step
requiring me to push and hold the power button. Nasty.
Clearly something is very wrong somewhere. <o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">This is what I see in dmesg before trying
the modprobe –r:<o:p></o:p></p><p class="MsoNormal"> [ 15.456135] hdpvr 1-3:1.0: firmware

the HD-PVR when I boot up, the hdpvr module doesn’t get
loaded, of course. So I can modprobe hdpvr and it loads
fine. Then I can modprobe –r no problem. The inability to
remove the hdpvr module could be related to the way the device
keeps recording sometimes. So I’m hopeful that fixing one
will fix the other. But I’m out of ideas about what to check
or what could be the source of the problem. <o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">I am running Mythbuntu so my setup for the
HD-PVR was pretty easy. Mostly just plugged it in and set it
up in the Backend setup. A few extra steps to enable the IR
flashing. And I did start with updating the firmware to the
latest using a Windows computer. <o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">I have checked my BIOS settings for USB

In those cases, cycling the on/off button with a 10 second delay
corrects the problem.<br>
If you are using the HD-PVR IR blaster, a reset does require a
reload of a lirc daemon if needed.<br>
<br>
I am using MythTV 0.27.3 on Ubuntu 12, and HD-PVR firmware 0x1e, the
most recent and preferred firmware as it corrects some issues. I
would definitely not mess with your firmware.<br>
<br>
Check your computer's USB port: should be rev2.</div></blockquote><br></div><div><br></div><div>Martin, when you say USB port should be rev2, you mean the USB port should be a USB 2.0 connector, right? I don't have USB 3.0 on this Mobo (P5N7A-VM) so that shouldn't be an issue here. And I have confirmed that I have the USB 2.0 enabled in the BIOS and with "HiSpeed (480Mbps)". The BIOS also has a choice for "Legacy USB Support" which I have tried disabling but that's had no impact on the HD-PVR situation. </div><div><br></div><div>Also, Martin, you may be seeing something similar to me when you describe that the HD-PVR looks like it is still recording. In other words, the HD-PVR is still streaming the data through USB but Myth has just stopped storing the stream. My concern is that this behavior would cause a recording failure on a future recording and that I wouldn't be aware of the problem to do the power cycling. Martin, can you try doing the "<span class="Apple-style-span" style="font-family: Calibri, sans-serif; font-size: 15px; ">sudo modprobe -r -v hdpvr" and see if you can unload it successfully? </span></div><div><br></div><div>From Greg, it seems that an older firmware is working for him (Greg, what Myth version and what distro and kernel version?). But for Martin, the newest firmware (which is the one I have - see above dmesg output) is working for him with Ubuntu 12. I am using Ubuntu 14 (with the same version of Myth, 0.27.3, but I don't think the Myth version has much to do with this issue). Is there anybody reading this using Ubuntu 14.04 (kernel 3.13.0-35) and HD-PVR firmware 0x1e? And if so, how are things working for you? Or perhaps, more generically, how is the HD-PVR working for people with Ubuntu 14? </div><div><br></div><div><br></div><div>Ken.</div></body></html>
