Hi all,

One of our systems us a small unsupported system that edits small DV jobs. We are now getting Video Overrun errors on digitizing DV25 firewire clips of 5munites +

PC Asus P4P800 Pentuim 4 ,1.5GB Ram , Two stripped sets on 4 Seagate SATA 2 drives of 250GB each. Quicktime 7.5 and Avid MC 3.0

When this system connects to the Mojo SDI it will digitise more than an hour of uncompressed1:1 MXF

We unplug all xtra connections to the machine including the Mojo to give the DV deck a fair chance on Digitising and no more than 5 munites load. The HDD are clean and empty, the machine ran on this config since June 2008 for about 30 Jobs.

Any knowledge will help us, I did search this topic but could find a solvable answer.

Thank you Braam

Solved: When the C drive is FULL, it can handle 1:1 because the file are written in numeriuos smaller file sizes. DV gets written as one big size, so than bombs out the buffer and Overrun.

If you're using the C drive for your media you will continue to be at risk of overrun and underrun errors.  Avid requires the media to be recorded on drives other than the boot or launch drive.  To do otherwise puts a significant load on drive access.

In any case the media will be broken up not because it's 1:1 or DV, but if it's an OMFI project or not.  Unlike MXF, OMFI has a maximum file size of 2 GB.

Thank you for the reply mate,

We do have "Two stripped sets on 4 Seagate SATA 2 drives of 250GB each." that gives us 1TB we use for media.

What I did'nt mention is that the C drive was full due to program files getting too large not the media that gets digitized on seprate Discs.
