mov playback video choppy when accessed from NAS device
I have a 2.5GB 640x480 30fps mov file that I created with QT Pro v6.x that plays very choppy video at 2fps (average) when accessed from my externally attached WD Netcenter NAS network drive. The sound however is fine. When I play this .mov in QT when it resides locally on my Dell Inspiron 8600 40GB internal HDD it plays fine - nice and smooth - both sound and video are good.
I'm wondering if this might be due to the speed limitations of the network drive over the LAN (but I'd be suprised, it's new) or the network drive device's CIFS file system that it uses.
Interestingly, this issue of choppy video is similar when the mov file is accessed from the CD/DVD drive (burned copy), which points me back to possibly an access speed issue (it has to be slower than the local HDD), although I think the CD/DVD uses CDFS which is another file system format other than the standard NTFS or FAT.
Is there anything that I can do to: A.) Adjust the frame rate in the video (it shows it in preferences/QT settings, but is unchangeable); B.) Buffer the video stream over the LAN as you would do over the www so that video is buffered before and while it plays; c.) Anything else.
I'm desperate to get this working because the files need to reside on the NAS device as they are too big and too many for the local drive. They also need to be played from there as it takes too long and is too tedious to copy locally everytime it will be played.
Alternatively, is there another mov player that would be more efficient in buffering a video stream from a sluggish device?
