Hello, we are currently trying to run multiple Direct RT files with both audio and video using version 2004.3.0.27. We have encountered the following problems:

1.Each video takes a very long time to load, but will load fine in WMP.
2.There are “glitches” in the video files, where the video stalls and runs as if it was running in slow motion. This seems to be random and does not affect each video the same each time we run it.
3.These problems occur when the files and stim are off of the external hard drive AND when the files are being run directly from the PC’s hard drive.
4.We have recently made two changes: 1) we increased the number of videos in our stim folder and 2) we increased the quality of the video files. Since doing this, we have a new problem: After several trials, Direct RT encounters an error and shuts down the file that’s being run. This is true for all of the .csv files that have been written, and is not dependent on which video is supposed to run next. We get this error signature when Direct RT attempts to open up a file (.avi):
AppName: executedrt.exe AppVer: 2004.3.0.27 ModName: pdvcodec.dll
ModVer: 2.64.1119.1600 Offset: 0001010e


Is there any insight or advice that you can give us to alleviate these problems? Thanks for your help.
