Good to hear Mike! Infrared can be a fun one to troubleshoot. I had a
problem just last night where my remote stopped working. I grabbed some
"freshly recharged batteries" and my remote still did not work. I finally
found that my rechargeable batteries would not charge anymore... New
batteries and all was good. It was very helpful to be able to get my mythtv
remote from the basement and verify this.
