I have this hd video concert, its 12 TS files. I have an alternative audio source that I want to replace with original audio since its very bad. So:

1) how would I rip audio from the ts files? (i need to rip audio so its easier for me when im trying to sync the alt audio). Does any software rip audio from .ts files?

2) how would I add my new alternative source to the .ts files? does tmpgenc does this? would I be able to make dvd menus?

3) I want my final outcome to be on Blue Ray DVD, still maintaing the HD format. I don't want to convert HD to regular DVD-5. how do I do that?

thanks!
