This isn't an answer to your question because your TV's electronics will be the source of THAT answer. "Which file will it recognize or need?" may be covered in the owner's manual OR at that website.
On our media servers - which are Windows, Mac or Linux computers - I use the VIDEO_TS.IFO file as the 'starting point'. This seems to be the genuine starting point for DVD players. On computers, I "associate" this .IFO file with starting up the Media Player, however. (It's also the Menu's Shortcut Target-File - so clicking on the on-screen menu's icon for this particular movie activates this VIDEO_TS.IFO file, which then plays all the subsequent files as if it was a physical DVD.)
I'm not certain this is how your TV will react, though. It may only 'read and play' AVIs or perhaps a select other single-file formats.
