If you have installed the miroVIDEO DC30 series together with a graphics
board that supports DirectDraw a digital overlay function is, in principle,
possible.
Please refer to the information given on our Website at:
http://www.pinnaclesys.com.
You can access the Live Overlay via VidCap, the Options Menu and the Live
Overlay command.
If the overlay display in a window does not work, go to the Windows 95 /
Windows 98 Control Panel (Control Panel, Display, Settings) and change the
resolution, color depth, and refresh rate, or ask your reseller for a new driver for
your graphics board.
Overlay quality
High resolution
This is the default setting. The option High resolution displays the video in
high quality in the PC window.
For this purpose Overlay Surface must be selected as representation mode, and
your graphics board together with the installed drivers must be able to produce
an Overlay Surface in the current resolution and color depth.
For displaying in overlay mode several MBs of image data must be transmitted
per second to your graphics board by miroVIDEO DC30 series via the PCI bus.
This is no problem for state-of-the-art PCs and graphics boards. If your system
does not offer the necessary performance, image interference might occur in the
video window. Only a section of changing size at the upper edge of the window
will be displayed fluently, in the lower window section the video will get stuck
again and again.
In this case, install a graphics board of higher performance or a faster mother
board in your PC. For the moment, choosing a lower overlay resolution might
help.
