[mythtv-users] Two mysteries

>Try USB 2.0 ports
Unfortunately this motherboard only has USB 3.0 on the back panel.  All the USB 2.0 ports are internal and I don't have the right cable to convert the internal header into something I can use.

>My experience with my IR repeater is that it can get signals from
unexpected places.  

I too have a fluorescent light that causes some IR but two experiments I tried seem to rule this out.
  1) I covered the sensor eye with tin foil and blocked all the light I could and it was still flashing.
  2) As soon as I power down the mythbox all the flashing stops (except for when I legitimately hit a remote button).  Somehow even when the mythbox is in a different room and only connected to the AC/DC converter (no ethernet, hdmi, or wifi) it still causes flashing on the dinky link.  Could it really be "polluting" the AC lines of my whole house?  I guess if X10 can do it maybe this crappy power brick can too.  More investigation to follow.

>The operation of IR receivers changed drastically after 10.04 - the
drivers for most moved into the kernel.  This tends to break LIRC
operation when you upgrade.  I found this page:

http://linhes.org/projects/linhes/wiki/Architecture_and_Customization

to be a great help in working it all out with my MCE remote and my
Hauppauge Nova remotes.  The page tells you what tools to use for
debugging each stage of operation.


Thanks I'll review that (and the USB 2.0 header) if I cannot get the flirc working tonight.

I read on the flirc forums that everything flaky about the Raspberry Pi is caused by cheap/bad power supplies.  Since I'm running on a recycled laptop brick I'm suspicious that the same rule might be apply to my system.  Perhaps poor 12V regulation is causing some/all of my problems.  I guess I'll have to see if I can find a high quality AC/DC converter with the right size power plug...  onward to google!

thanks,
Matt
