Hi
I have burnt the dvd using toast 9 drop the .ts file in create dvd
toast does it all i.e. demuxes the file and creates Video TS folder and Audio TS folders. It also puts time markers every 5 Mins same as commercial DVD recorders and then burns the dvd. I have not tried recordings with HD on Blue ray yet. The only problem is it takes time i.e. a feature length of 1H 45 Mins takes as long as 4 hrs. The beauty is that all the recordings on BBC and CH 4 Channels start at the right time so you dont have to edit the starts
Have fun
