Hello, I checked it lot of time and ALWAYS that there is a program
change on the guide, there is a 100% CPU usage with mythpreviewgen
process, it takes 2-3 seconds and then disappear, but it stop the
LiveTV. This is really annoying problem. It occurs for me on LiveTV.

I am not an expert, I think that it is related to the preview image
generation. Hope some developer will fix soon. This is the biggest
problem that I have with MythTV.

I have same problem on two Nvidia ION board FE/BE boxes.

Best regards.
