I recently acquired a Mac Pro Quad Core with 2.8GHz Intel Xeon W3530 and 6GB (3x2GB) RAM. I've never had trouble working with MP4 files before until now. When I work from the Glyph, with the MP4 files they go out of sync and the audio skips and stutters but only from a select group of MP4's. If I transfer the files to my desktop and work from them there, they are fine; most bizarrely, if I transfer files from Glyph drive to desktop and back to Glyph drive, they are fine also. Any suggestions as to how I can continue working from my Glyph drive-it’s so much more convenient for me.
This is caused by the fact that the Glyph further bottlenecks a system that is underpowered to start with, at least when you do not use the eSATA connection. Even with eSATA the Glyph is around 70% slower than a modern disk, but when using USB2 or FW400 it comes to a crawl. Add to that the very limited memory, the probable lack of hardware MPE, then there are numerous factors to cause this behavior.
Thank you for the reply. It is quite bizarre because I am now editing from the same footage off of a $100 WD drive, quite concerned with this Glyph issue because I have two 2TB Glyph drives and wanted to further my arsenal with an 8TB but not if I cannot use them to edit off of.
