The most recent tool for displaying closed captions on the tivo is
tivovbi
(written by embeem).
The 1.03 version was announced on the TiVo Underground forum on
this thread,
though you might want to check out
embeem's download directory
in case this page you're reading becomes out of date (if so, please
tell me!)..
It lets you display not only closed caption info, but XDS channel info as
well. With the right options (-ctd), you can see iPreview info, as well
as what's probably the seperation between clips in paid programming for
the new clips in 2.5.1 (see here)..
Here's a sample of what it looks like in OSD (On-Screen-Display) mode
(text can also be output to stdout):
(Click for movie)
Lastly, for those who need to see a Usage string to feel it's real,
here it is:
tivovbi [ -t | -o ] [ -c ] [ -x ]
DISPLAY MODE:
-t text output
-o OSD display (requires -c)
DECODE:
-x XDS data (requires -t)
-T set clock (requires -x)
-c1 CC1 data
-c2 CC2 data
-d DEBUG MODE (requires -t)
