Adding subtitles to .ts VC-1 stream

[tomerwiz]

hello,
I have a .ts stream which is encoded in VC-1, now I would like to add embedded subtitles into the stream, which invlovles of reencoding the entire stream.
Which codec should I use to reencode the stream.
Should I use h264?
Is there an easy way which doesn't need reencode?

In case I reencode the entire ts stream into a new codec like h264 or x264 will I be able to play it on HD-DVD or Blu-ray players?

If I convert the .ts stream into .mkv file is there an easy way of adding soft subtitles into the mkv, will HD-DVD and Blu-ray players can play mkv files?

Sorry for too many question but I would like to make it done.
Thanks for helping

vc1 and h.264 is mandatory for HDDVD and BR so with proper profile and proper level you should be able to view h.264 video (compressed for example by x264), support for mkv is a free will of the manufacturer of hd player. You should verify that your player have such option as support for mkv files. If you author hd disc accordingly to the specifications of HD-DVD or BR you should be able to view embeded subtitles (subtitles must be compliant with specification of the HD-DVD or BR)
