Some files in the playlist do not play
All files on a playlist channel must be the same type.
If some are elementary stream, video only, and others are program
stream, audio and video, some files are automatically skipped in
order to keep playback running smoothly.
SMPTE time codes are not recognized
properly
Some SMPTE tracks loose information during compression and
may not initiate events as required. It is recommended to encode
these tracks hot, adding approxi6 db to the track while
encoding. Again, testing is essential to account for variances in
encoders and SMPTE devices involved.
Eliminate Noise with Filter
Simple audio filters, used at the installation site, are also useful
in eliminating noise and cleaning up the SMPTE signal.
