I have a Myth Frontend that has been happily working over S-Video to a 27" Panasonic CRT TV.  Recently, I bought a new Panasonic 50" 50PX77U plasma, so my intent is to connect this display using DVI-HDMI, rather than S-Video, for obvious reasons.

Anyway, since I have not yet configured xorg.conf for DFP output, I simply plugged the S-Video cable into the new plasma as an interim measure.  When I did this, lirc started behaving oddly.  It just does not respond to my remote, and when I run irw to test it out, it very rarely (if ever) picks up the command.  If I simply unplug the S-Video cable from the plasma and put it back on the old 27" CRT, everything returns to normal.  Here, irw echos each and every command flawlessly.  Mythtv responds flawlessly to my remote control as well.

I have come to realize that the plasma TV is creating sufficient infrared interference to disrupt my remote control operation. 

Any thoughts on what can I do to correct this?  Some sort of filter?  Should I try a different IR receiver?  I use this one now:  http://saturnpc.com/index.php?main_page=product_info&products_id=1

Would an RF remote control be a good solution?  Any particular model?  Not sure how well this works with lirc, but I have read that it does in fact work (it does seem curious that RF works with lirc since lirc stands for linux infrared :) )
