closed captioning troubles VV12

I'm in the process of learning about closed captions. I have a Vegas 12 project where I've added the markers and txt, it all appears correct in preview. I can render to MXF and reimport & the captions are there. I can render to MPG2 and reimport and the captions are there. I cannot get a media player (vlc, wmp, qt) to display these closed captions.
I have been given a "known good" file to demonstrate player capability so I know how it should work in the player. I've also used media info and cannot see a meaningful difference between my file and the "known good" file. They both report two text streams.
Any one have luck with this for file based viewing? What formats are you rendering to? What player are you using?

Thanks much,

Vegas embeds the text into the WMV render but only when you use TEXT from the Command drop down list in the Command Properties requestor and put the text in the Parameters window. It's not like normal CCs for broadcast, in fact the text is displayed below the window and in a small roman font.

Also WMV player doesn't default to show captions. You have to right click in the window and select Lyrics, Captions and Subtitles/On -if available.

Thanks Bill,
Our target is iBook for the iPad so I don't think WMV is the solution we're looking for. There is a lot of info in the manual and this page: http://www.sonycreativesoftware.com/add_closed_captions_to_your_video_project
and they indicate CC can be part of MXF and MPG2 files but I can't get it to work.

Is anyone having success with this?

update:
I can get the mac application Compressor to merge the sony made SCC & MXF to a prores MOV that then displays the closed captioning as expected in QT. I can use Camtasia studio to make a SRT format caption file that VLC will recognize and display properly.
What am I missing? Will vegas make a singular output with closed captioning? The only posts I've found are WMV with a TXT playing together in WMP. This doesn't meet our needs.
Thanks for any suggestions or experiences,

Under scripts are different export options for Closed Captioning.
Also, there are a lot of instructions on-line on how to add cc to qt

Thank you Dave.
The page you link mentions using "movie captioner" to generate an "embedded quicktime" Can I assume then there is no way to do this with Vegas? The manual and guides seem to indicate support for MXF and MPG (2).

Vegas can export many types of CC files, but you have to embed them manually. It only encodes MPEG and other uncompressed files I believe, with CC.

I am working with Sony support to render a video with embedded closed captioning. So far no success...

After some work I can make an MPG2 file but the captions still do not display in WMP or VLC. Here's the suggestion I used:

"... choose the program stream NTSC template, click customize, change output type to MPEG-2, change Height to 486, then change profile to High and leave the Level at main, ... to render an MPEG2 file with embedded captions. "

Unfortunately the check box "include markers" is greyed out in the render window... hmmm...
