time to run calculation

Hi All

Following on from the Yamaha Amp questions , the new version now gives me un-fuzzy audio on my 5.1 MP4 's but the time to run is all wrong , over 500 hours. How is this calculated ? It was a problem in the previous version as well.

it's because the file is transcoded probably. the proper length is sent to the device but it chooses to do its own calculation
