Can I re-encode these files to use the same formats as HD-DVD and Blu-Ray? I guess VC-1 and H.264?
Do any of you do this for archiving? I would imagine the same pic quality...any comments on this?

Sure, you can transcode VOB to h.264 with AAC audio in a matroksa container and get pretty good results. You are still going from one lossy compression to another, however, so YMMV.
It might not be worth the effort, though. Takes a lot of additional horsepower to encode and playback, without any benefit beyond a bit of space savings.

Ok now for the $64 000 question. Can you play .TS files in an HD-DVD or Bluray stand alone?

You sure can...I've done it with Toshiba HD-A1 several times. It does require some repacking of some sort, but no re-encoding.

Now Toshiba was thinking ahead on that one...

There are a whole slew of $300'ish network players will play raw .ts files, but I haven't seen any mainstream name-brand players that will play an HD .ts file off optical disc - especially not any HD-DVD/BD STB's.
Lyd mentions transcoding VOB to h.264 - presumably he means SD DVD. Yes, there are tools that do that very easily. But, you're talking about re-encoding HD TS streams. THAT sucks. Even with a super-fast machine, encode times are LONG (as in overnight for a single show - for a fast machine).
Given that you'd be going from lossy to lossy, only gaining about half the space, and considering the horrendously long encode times, and given how cheap drive space is, right now it's just easier to archive the MPEG-2 stream.

Is it an easy conversion to MPEG2? I noticed Ice Age II is MPEG...

Most TS files ARE MPEG-2 files, but yes... there are lots of tools that make MPEG-2 TS files.

can't get away with just changing the file extension can we?

From what to what? Some apps will play a TS even if it won't recognize the .ts extension, just be renaming it to .mpg. So, sometimes you CAN get by just changing the extension.

Yep that's what I was hoping.

Oops, right you are, he is talking about Transport Stream. He clearly says .ts files, but I replied as if he was talking about the contents of a Video_TS folder. I really need to learn not to post first thing in the morning while coffee is still brewing.

Ben, how did you play .ts files on an HD-A1? Did you burn it to DVD in some format?

Gary, there's a MASSIVE thread on AVS about how to take HD .ts files from satellite or OTA boxes (and more recently MPEG-2-based HDV cameras), and using VideoRedo to edit and Ulead DVD Movie Factory to author an HD-DVD from the transport streams. You can burn it on a standard DVD +/-R, and play it back on the Toshiba players. It got a little more difficult with the second and third generation players. The first gen A1 and XA1 players were bulletproof and will play practically everything I've thrown at them. The newer players apparently have problems with higher date rates, certain types of discs, etc.
http://www.avsforum.com/avs-vb/showthread.php?t=705146
I've made a couple of dozen discs and I'd do it more if I had the time. It take some time to edit, then save the file, then take it into MF, make an image, then I have to move it over the Mac to burn because I don't have a DVD burner on my Windows box. It's pretty cool, though not having to fool around with the HTPC. I've got a PILE of movies stacked up just waiting to be formatted and burnt.
Some movies will fit on a DL, others won't. I've also burned a few HD-DVD-formatted DVD-R's from video I shot with my HDV cam, edited with Final Cut Pro and authored with DVD Studio Pro on the Mac. Those work nice, too. Something very cool about seeing my own HD video playing in HD on an HD player. Looks beautiful.
