Sound Problems - Optoma DV11 User Manual

The type of disc you inserted might not be supported by the in-
ternal DVD player. If so, you can not play this type of disc. Try a
different disc.
For a DVD, check its region code. Most DVDs have a region code
marked near the center hole. Compare its region code with the
region code for a DVD that plays properly on your projector. The
projector can play DVDs from only one region.
If a disc does not automatically play:
A disc automatically starts playing only at the time you insert the
disc. If a disc is already loaded in the loader, press the [Play] button
to start playing.
Make sure the [Power] or [Stand By] button is pressed. If the pro-
jector is powered off, nothing happens to the internal DVD player.
If a disc skips and does not continuously play:
Check the DVD player isn't in [A-B] repeat status.
Make sure the disc is completeness, not scratch, dirtiness or warp.
If so, try to clean disc or press [Goto] button to skip to next chapter
or title.
If some images on a CD do not show:
Some images with very high resolution (high number of pixels)
cannot be displayed. Convert them to standard format with a lower
resolution.
