If you want the disk to be readable on an Amiga, then you need to write it as RockRidge filesystem or ISO Level 2 (31 char) otherwise you may have problems with the inbuilt CD reading capabilities of the CDTV/CD32/A570
If you have an Amiga with CD ROM drive (like an A1200, A2000, A600 etc.), and the likes of CacheCDFS or AsimCDFS, they should be able to read Joilet CDs (works for me) but UDF may be a bit of a grey area (never tried UDF filesystem on an Amiga before).
