High Definition Video on Inspiron E1505?
I can't get high definition video to play stutter-free on my new Inspiron E1505. Intel says the GMA 950 is optimized for HD playback. Apple Macs with similar hardware specs (1.83GHz Core Duo, Intel GMA 950, 1GB Ram) play HD video without a hitch.
I have tried installing the NVidia PureVideo decoder: no improvement. I noticed that when Windows MCE first started up, it played a tutorial video that looked like Hi Def to me, with no problem. Why can't I play my own HD (720p or 1080i) video files without stutter?

- Standard Def DVDs and video (480i/480p) work fine. I only see the stutter on High Def (720p or 1080i) mpeg video (or tp streams). If play an HD video that has been recoded to DivX, it plays fine with no stutter (but, presumably, lower resolution). I've tried all the settings available in the Nvidia PureVideo decoder, with/without HW acceleration, etc. -- none help.
CPU usage while playing HD video (with HW acceleration) is around 20-25%. It seems like it pretty much has to be the video HW and/or driver.
Dennis - It looks like it's a network problem rather than a video problem. If I play the HD video files from the local drive, or if I switch from wireless to wired (100MB) network to open the video files on the server, the video stuttering goes away.
A 54MB wireless network should be sufficient bandwidth for HD video. Maybe I need a new/better wireless router.
