[mythtv-users] Sudden 'disappearance' of dvb tuners

[Jason Hiller]

John,

That my have been my post.  I pasted it below.  I have not found a solution for this.  My next step was to either upgrade to 0.26 or downgrade per the information in the thread I found (listed below).  Let me know if you have any luck.

<---- Below is my thread --->

Just found this thread.  They are suggesting the issue with the HVR-1600 was introduced with Myth 0.24 and persists in 0.25 (not sure about 0.26).  Is anyone else experiencing this issue?

Thanks for the input. Unfortunately a reboot doesn't work for me. I have rebooted several times with no luck.

I currently running a HVR-1600 along with a PVR-150 and PVR-500, under
Fedora 17 x86_64

My HVR-1600 does this occasionally also. I some times get a red
recording and sometime a grey recording. Just to complicated matters my
over the air tuner ATSC some times is detected and other times not.

I'm guessing there is some driver issues since I tend to reboot the
computer and some point both the Analog and ATSC devices seem to get
recognized.

I just haven't spent the time so see what is causing this. So I'll have
to keep an eye on this thread.

        Andrew

I just rebooted my Fedora 17/MythTV 0.25.3 main box after upgrades that included kde 4.10.2 and dvb-apps.  Mythbackend couldn't see any tuners. dmesg showed the pci cards ok but no firmware load for the usb device.

Mythtvsetup didn't see the cards either, until I tried running femon for each adapter.  pci cards then worked, usb not found.  Unplug/replug usb; firmware loaded and it's probably ok.

Someone else posted recently about tuners that worked ok after being used once, but I haven't relocated the post.  This feels similar.

This box is non-standard at present because the f17 nVidia packages that I would like aren't at ATrpms, so I'm still running an f16 kernel - and wondering where to go next!
