Happague HVR-950Q woes

Hi guys,

I'm new here, and I got a brain teaser for ya. I've got MythTV 0.23 running,
using a Happague HVR-950Q USB stick tuner. I have both the ClearQAM and
analog tuners working correctly. But, when I'm using the MythTV front end,
eventually, my keyboard becomes nonresponsive, and I have to alt-tab out and
kill the frontend.

The tuner works just fine. However, the keyboard becoming nonresponsive is a
deal breaker. No such thing happens when using XBMC to connect to the
backend and view live TV, so I BELIEVE it's a frontend issue. dmesg doesn't
bring anything useful, either.

I'm using a ZOTAC ionitx-g-e mainboard, and a HP wireless USB keyboard. I'm
kinda leaning on it being that the USB bus may be a little overloaded, and
that's why, but that wouldn't explain why I can alt-tab out. Where should I
start troubleshooting?

Oh, and has anyone gotten the remote to work?

Thanks ahead of time,
Rob Lynn

It's not clear to me why you think this has anything to do with the
HVR-950Q (as suggested by your subject line). Especially if you are
able to "alt-tab" to switch away from mythfrontend (suggesting that in
fact the keyboard is working).

Regarding the remote control, it is not supported under Linux (and I
have no plans to add support for it in the immediate future). Given
how hard it is to setup remote controls under Linux, I would strongly
advise you just spend $20 and buy an MCE USB remote control receiver
which will work "out of the box".

Cheers,

Devin

Rob,

Can you tell me how you got the 950Q analog tuner working properly?
I've been working on it for a while. I can usually get the video to
work, but I haven't gotten the audio to work reliably. I'm running
Mythbuntu 10.04. I haven't had any keyboard trouble on my end, but
I'm using a wired keyboard.

Carl,

I had two issues with audio: First, my TV didn't like a 32kHz sample rate,
giving me weird sounding audio. So, I had to change that to 48kHz. Second,
the audio kept dropping, and my hunch was that it was video frame-dropping.
It seems to have improved quite a bit since I moved to a 7200rpm drive. So
for you, it could either be that, or maybe an overloaded USB bus.

Devin,

I only thought it was the tuner's fault because it freezes up when watching
video in LiveTV, but nowhere else. Last night, when the keyboard stopped
responding, restarting the frontend resulted in a segfault caused by
libQtCore.
