I put the .TS, .MPG, or .MP4, or other files on a server on my home LAN, and play 'em back with a Western Digital Live Plus media player in the living room, in 720 or 1080, or whatever.
This is discussed in other threads, and I won't repeat it here.
Do you want to make compatible DVDs other people can play, or just have your HD shows on discs for your own use?
Reason I ask, is there's an actual solution to that problem!
Several friends have the top of the line Samsung BluRay players, with LAN access so they can do Netflix, Youtube, and more.
So, with all the required codex, they can also play home made DVDs with files in all the common formats, including HD .mkv, .mp4, .avi, etc.
But if all you want to do is make real DVDs others can play, then a program called ConvertXtoDVD is what I use.
Don't have to know much; put in the files, fire it up, and walk away.
Oh, and I edit with VideoReDo, regardless of the format, but that will cost you a couple of dollars.
I've used it for 5..6 years.
