Extras
Extras (Figure 35) are features of the AVStream driver that are new, not fully defined, or subject to
change. Extras may also include workarounds to apparent DirectShow issues that are expected to be
resolved fairly soon.

Extras should be expected to change more frequently than other aspects of the driver.

Closed Caption
Timestamping This control is a workaround to what we currently believe to be a
problem in DirectShow with capture of CC to AVI files. If you attempt
to capture a CC character pair stream along with a video stream to an
AVI file with Normal timestamping, the file becomes extremely large
and the capture fails within a few seconds. AVI-Compatible mode
allows capture of CC to AVI. Unfortunately, the problems with
timestamping mean that time synchronization between the video and
closed caption streams depend on their physical interleaving in the file,
so that time synchronization is quite poor. We do not have a
workaround for this at this time. For all applications other than capture
to AVI, this control should be set to Normal. WME9 among others
requires the Normal setting if CC is used.
