Troubleshooting Tips

❏
Incorrect channel to drive mapping in multiple card systems
with multiple content drives. For more information see
“Multi-Card Servers” on page 29.
"Latent Images" or "Flashing" during
playback
❏
Incorrect source timecode provided or improperly closed
encoding session. If the incorrect timecode for a file on
tape is given, it is possible to encode a frame or two of
trailer or header information from the tape. Often this
"extra" frame may be seen only briefly and may appear as a
visual "flash" on the screen during looping playback.
Review the original source material and determine if the
timecodes are correct for the tape, or if the encoding session
was actually started and closed on the correct frames.
❏
Playing MPEG 1 and MPEG2 files back to back: The
resolution switch from MPEG 1 files (342X240) to MPEG2
files (720X480) causes a "latent image" or a "quadrant
display" of the last played file's image. The only way to
perform seamless playback when using a playlist of files is
to insert an encoded "black file" with blank audio track,
between MPEG 1 and MPEG 2 files. The black MPEG file
preceding the playback file should be of the same standard.
In other words, prior to an MPEG 1 file the "black file",
with a blank audio track, should be MPEG 1 and vice versa.
Changing the driver parameter "InitOnOpen" to "1" may
also remedy this problem, as long as back to back
"seamless" playback is not desired. Each file must be
"loaded" individually prior to playing. (You can use the
