Possible bug with SCC / closed captions?

Possible bug with SCC / closed captions?
Fri, 13 Apr 2007 14:05:52 -070
Hi,

I just want to post this so that anyone else that runs into the same problem I
did might be helped...

Like a lot of other people, I was having trouble getting Encore to properly
encode closed captions. I tried over and over with no success. I tried placing
the SCC in field 1, field 2, both at the same time, etc... I tried with and
without re-encoding the already compliant MPEG-2 file being used as the source.
Still no luck. No matter what I did I could not get Encore DVD to properly
encode my SCC file on the new DVD.

However, I did have one clue that eventually helped me figure out a workaround.
Although I was not seeing the closed captions from my SCC file, I was seeing the
original closed captions from the original VHS videotape my source file was
captured from (I should note that even then, I wasn't seeing the original closed
captions on standalone DVD players...I could only see them with PowerDVD...) So,
I began to ask myself why Encore DVD was not overwriting the original line-21
captions with my new SCC file. It was as if Encore DVD was completely ignoring
the new SCC file.

Well, to make a long story short, I found that I could get the new captions to
work perfectly if I removed the old captions from the original MPEG-2 source
file first. Apparently, Encore DVD will not overwrite existing line-21 data (a
bug, I'm guessing...) even if the user properly loads the new SCC file.

For anyone who is having this problem and wants to try my solution, download
ReStream and remove the user data from the existing MPEG-2 file. The new file
without user data has now worked for me every time I have tried it. Actually, to
be honest, I'm not really sure if this bug pops up only when existing captions
are detected or if just any user data will trigger it. So, anyone who is having
trouble getting SCC to work with Encore DVD and successfully uses this
workaround, post back here and maybe Adobe will do something about it.
