I noticed, as I spend some time reading his avid note taking, and use
dvd+rw-tools quite often.

The "-UDF"/"-udf" switch, as documented within the mkisofs man file, sectors
20-256 are supposedly wasted. I calculated this to be about 236 sectors * 2048
bytes (as 2048 bytes are contained within one DVD sector), is about 483,328
bytes, or roughly ~483MB. However, speculating upon the wording of the man
page, the usage as you already stated, is likely just minimal.

On that note concerning the "standard", my gut instict is to just use the
"-UDF"/"-udf" options. The wasted space is likely a moat issue, and only a
concern when preserving a copy of copywrited DVD/BD material. My DVD/BD
recorded media should be viewable via a very basic file system viewer/menu on
TV standalone bluray players, manually selected and viewed/played, as long as
the standalong player has the decoders.
I'll do my research based on what you stated here, as I've been using CLI
I also *just* noticed the ability of using cp/rm (POSIX) tools with
DVD+RW/BD-RE not requiring the Linux kernel pktcdvd driver (supposedly marked
deprecated as of 2016), although I have yet to test writing with larger files,
likely expect more noise or random writing at 2kb writes instead of 32kb
Remember, the intent of this thread is TV standalong bluray players, not
related to PC equipment. I just desire to make non-copyrighted files such as
photos and recorded video only viewed/playable without nice looking menus,
other eye-candy, or automatic playback, etc.
I might have to buy a cheap standalone player to ensure the player is acting as
it should with the chosen recording process, rather than just assuming.
Surprising I cannot find more information on the Internet concerning a
simplified process, and guessing most just run-off and use the graphical tools.
Or, people have been using mkisofs (or growisofs with)
-dvd-audio/-dvd-hybrid/-dvd-video all along.
