MPEG-4 (AVI) 720p High-Definition Playback

For MPEG-4 (AVI) playback we again used PowerDVD Ultra and again played the files from a hard drive instead of disc. The 720p trailer we used was for the movie, Ray, with a bit-rate of 3,336kbps in DivX 5 and two channel MP3 sound at 191kbps. For 1080p playback we used the Elephants Dream movie-short which is encoded at a bitrate of 9,998kbps and six channel AC3 sound at 448kbps.



The 9300 IGP again showed its prowess in DivX movie playback, although at 720p the difference was only three percent. At 1080p however, this increased to seven percent but the difference wasn't nearly as much as with Blu-ray playback.

WMV9HD Playback

For WMV9HD playback we again used PowerDVD Ultra and again played the files from a hard drive instead of disc. The 720p trailer we used was for the movie, Doom 3, with a bit-rate of 6,790kbps and two channel WMA3 sound at 440kbps. For 1080p playback we used the The Living Sea trailer which is encoded at a bit-rate of 9,847kbps and six channel WMA3 sound at 384kbps.



Again the GeForce 9300-ITX WiFi proved to be the faster motherboard, with noticeably lower CPU usage but again the Intel DG45FC wasn't as far behind as with the Blu-ray playback tests.
