jlb - First hoping to make silk purse out of what might seem now to be a sow's ear.
Did you keep the .vro file that would not burn, or did you ditch it?
If you kept the file you might try a work-around that will make something out of the .VRO which is useful.
Simply change the file extension from .VRO to .MPG.
See if it can then be played as is in VLCPlayer.
For burning to DVD --
Open the .MPG file in a video editor and split it into two smaller halves - one for each half.
(This may not be a requirement, but it will make for a nicer DVD).
Open your DVD authoring software -
if you have the same - and add the two new .MPG files to make a standard DVD.
OK - that deals with half of what jlb is getting at in his post, and I believe he is making directly, or between the lines some excellent points.
Uniformity of presentation - One thing is already handled, the specific file type and size is declared by the torrent server and you can see it in the drop-down box. So, there shouldn't be any surprises about what the file is called.
I think jlb is also asking for some kind of uniform declaration of the specifics of the file package, I think that is a great idea and we are not that far away on most of the torrents.
Typical data of interest - is it all one file, or is it really a collection of files. Sometimes we can tell from the drop-down box, sometimes we can't. A simple read-me file (like timbuck2 always included) would help, alternatively a direct declaration by the torrent maker of what it is they are presenting can only help (see Rocketman's servings for example). Either way, what the file is and directly or indirectly, how to use that file on receipt should be part of what we make clear.
BB, first let me echo the appreciation that others have expressed for the work you are putting into making media available. I know it is a time-consuming activity. Still, if you will allow me - just a couple of points. No-one should claim that .VRO files will play on TV, well, not on any TV. It all depends upon the hardware. Assuming the recipient of the file is able to get around the file format and size issues and burn a DVD of some type, the file (and thus the disc) itself may not be recognized by a standard DVD-Player.
Secondly, you can take this to the bank, Nero will recognize .VOB files, they are the
default type of media file for a DVD.
