Troubleshooting Tips
38
Video blocks or stutters when starting
playback
❏
Be sure buffers are fully loaded before calling a playback
command. Usually following the initial buffer load, a delay
is required.
Overall blocky or distorted playback
❏
Make sure the file is not a transport stream. These files
typically have a .m2t extension. Visual Circuits MPEG
decoders do not support transport stream files.
❏
Try playing another file or a Visual Circuits demo file to see
if the problem is specific to a file. If so, the data may be
corrupt.
❏
Make sure that NTSC is not being played to PAL or vice-
versa (the vertical resolution is 576 in PAL and 480 in
NTSC).
❏
Check that M2Ps (program files) and M2Vs or M2As
(video or audio-only files) are not mixed on the same
channel.
❏
Possible damage or faulty channel or decoder card. Use test
files and try other channels to verify. Always try one file
and one channel first as a base line for troubleshooting.
❏
Verify ATA 66 to ATA 33 compatible components and
drivers. A different IDE bus driver may be required for
proper system performance.
Poor Onscreen Display (GIF) overlay
❏
Refer to the "On-Screen Display Guidelines" document for
details.
Problems using the API
❏
Make sure you are using the standard C calling convention.
Refer to the SDK documentation for questions.
