Any TV Tuner card or software or a combination that allow recording closed-caption?

I'm looking for an TV Tuner card or software or a combination
that allows closed-caption recording. So that I can still see
the closed-caption when I view the recorded video on
my PC. Thanks.

The Software that comes with the All-in-Wonder, HDTV Wonder and some other
ATI products, MMC(MultiMedia Center), can record in ATI's own proprietary
VCR format. That contains the CC. Some of the newer products come with
CMC(Catalyst Media Center) software that AFAIK is made by Cyberlink and
don't know that it has a format that supports CC.

A couple of people have asked recently if anything else can play VCR files.
AFAIK nothing but MMC can play them.

This may vary greatly by capture card and playback software.

For example: An OnAir HDTV capture device will display broadcast
CC. After editing digital captures with VideoReDo, files played
back via its player will also display CC, while Media Player
Classic will not display CC from the very same captures.

Older Hauppauge SD H250 or USB2 capture devices do not pass on
CC at all. Perhaps contemporary Hauppauge devices/software may?

Subtitles can be muxed into .mpg but CC can be other than
subtitles.

"Bill's News", what is shown when looking at the file under
the "Filters" in Media Player Classic? There should be something
like the following:
____________________
Properties...
* Video (0000,e0,00)
* Audio (0000,c0,00)
* Subtitle (0000,??,00)

Hi Ken,

in the only file I checked, MPC shows:
video 0000,eo,00
audio 0000,bd,80
subtitle 0000,00,00

Neither MPC nor VLC has a sub-title selection enabled for these
HDTV captures.

Playback via the OnAir player will show the CC, as it will
during capture.

As far as I know, which ain't much, there are no subtitle
"tracks" transmitted OTA - so it's either CC or nothin'.

I've recently written to OnAir asking about capturing CC to a
separate file. Their answer: it is on the list of user
requests, but not near the top.

BTW, it appears that in order for CC to be retained in the OnAir
captures, CC must be enabled before capturing, otherwise there
will be none in the post capture file.

Am I to gather from your reply that you are able to get CC
playback via MPC (or VLC) from your HDTV captures before/after
editing with VRD?

It seems to me that HDTV Wonder isn't capable of recording
closed-caption. Its Media Center option page doesn't offer .VCR
format for recording.

The ATI HDTV Wonder records in .vcr format natively.
Never record to any other format except "Native" for HD recordings. Then
use the library program to convert the recordings to mpeg2 HD. You will lose
program information and resolution is native is not selected for recording.

It's always some limitation here, some limitation there. Why is
it "HD" in "native" mode only? Why can't MMC record in other
modes now when it was able to capture analog TV signals in a
number of resolutions with old AIW cards five years ago?

Well, with the analog card you had to A-D convert it to record it and
unless your sample rate is a multiple of subcarrier, you also need to
decode the color from the luma.

In DTV, they're already sending you a digitized stream ready to record
or view or whatever. Processing is almost trivial for recording and
the remainder is mostly done on the video card. Coverting to a
different format on the fly requires LOTS of processing and to what
end? Down-res ? Why?

BTW, the captioning remains in the data after exporting to MPEG and
the captions can be viewed with the ATI file player though Windows
media will only play the video and audio but no captions. Of course I
was using ver 9 so I don't know what later versions might do.

Somewhere on the ATI site, there is a FAQ that states that if you want to
record CC, you must record in "native" format. Any other format used during
recording will not preserve the CC information in the recorded file.
