Operation
Page Table Entries
Some Windows systems don't allocate enough resources for frame memory PCI cards
(particularly under Windows 2000). If the Xena card does not work after you have installed
the board, driver, Control Panel, and then rebooted, the registry may need to be edited
manually because the system did not allocate enough Page Table Entries for the driver to load
correctly.
Caution:
Editing the registry should only be attempted by persons with understanding of
the registry and proper editing methods. Failure to edit the registry correctly can result in a
system that will not boot or operate properly.
Before changing the Registry, take the usual precautions (backup the Registry, etc.). You will
need to modify the following:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session
Manager\Memory Management\SystemPages
It is usually 0 (which signifies that a default value is used). For XenaHS boards, you
may need 85000 pages. Reboot after changing this setting.
Note:
You will need about 20000 pages for general system use, plus the number of pages
needed for each AJA board installed.
XenaHS: 65538 pages
XenaSD: 32769 pages
XenaSD2: 32770
XenaHD and XenaHD2: 65538 pages
Firmware Initialization failure
Any time the Control Panel is started, hardware configuration registers are set to the values
stored in the registry; but this operation can fail if the firmware initialization is not complete.
Video Format, Reference Source, and Video Processing settings may need to be 'reset'
manually. If, after a system start-up, the board is not functioning correctly, try resetting the
Video Format and Reference Source.
Windows Media Problems and Solutions
Windows Media applications—No Xena device listed. If, after Xena installation, the
Windows Media application does not list Xena as an available Capture Device, the
device installation may be incomplete. Try rebooting the computer to save the new
device information. If the application does not process video after the Xena device has
been selected, the application might not be asking for any formats supported by Xena.
You may be able to change some settings in the application to make it work. First, try
using the most basic applications, WMCap and SoundRecorder, to see if the Xena is
indeed functioning and connected properly.
Windows Media—Filter cannot report capture information. If WMCap reports "Filter
cannot report capture information "in the status bar (instead of the captured/dropped
frame count), make sure you are running DirectX version 9.0c or better. From "Start /
Run...", open "dxdiag." If the "DirectX Version" is 8.1, Capture filter registration will
be incomplete. Other symptoms with 8.1 include: WMCap menu item "Options... /
Video Capture Pin" does not bring up the Properties dialog; Windows Media Encoder
can not bring up the Mixer from the "Mixer..." button in the Audio Panel; and some
applications may be unable to capture video.
