Couldnt yield much googling.
If you are burning data to bluray for archiving purpose,
What is the preferred file system to use ?
UDF 2.50 (which WinXP cannot read natively) or ?
You could use UDF 1.02 or 2.0 that are WinXP compatible.
Imgburn ( free burning software ) defaults to UDF 1.02 and works perfectly with my players and windows XP and Vista.
