The only thing I changed in my setup was to connect the PVR-150 to a
different SchedulesDirect lineup, and of course to use a different
channel changing script.  The raw VBI is still being seen by the
PVR-150, but the sliced VBI is not working.  My HDHRs are still
delivering closed captions properly, so it's not a problem in the
high-level myth settings.  The recordings listing does indeed show the
"cc" logo, and captions show up on a direct connection to the TV.

The STB has to artificially inject the VBI signal into the output for
captions to work.  One possibility is that the VIP211 and VIP722 do
this in a slightly different way, and the 211's mechanism is confusing
my card's sliced VBI capability.  Another possibility is that my
PVR-150 has a different chipset than yours (mine is the low-profile
version which may use different drivers).
