Windows Media Encoder 9
For this benchmark I grabbed the 1080p flight video from the Microsoft website and used the free Media Encoder from Microsoft to turn the video into a file for download with video at DVD quality (2Mbps CBR) and audio at CD quality CBR.

MobileMark 2007 is a synthetic application that strains the battery on the notebook and gives a score for the run time while doing common computing tasks. I tested the Gateway MD7826u with the DVD playback test and the run time for the machine with a fully charged battery and settings on high performance are seen in the screen shot below.
