This has been seen with short video clips of 1MB or less on both ABVB and Meridien systems. On Meridien, this will happen with 1:1 uncompressed video with files that are 4MB or less. In most scenarios, video files will be larger than this thus most users will not see this problem. The current workaround is to digitize a slightly longer file.This has been seen in software versions 5.1.1 and earlier and should be fixed in a later version of AVoption and AVoption XL.
