The freebsd iso file was not fit to my 4.7Gb dvd-rw disc

I have experienced the same issue. Currently I don't have any other DVD type nor Flash/USB.
Maybe I will try an older version or wait a bit for the fixed.
I just wanted to check how my machine supports FreeBSD, so nothing it's nothing urgent.
I have found this bug report recently, but earlier I have started this as a topic on the FreeBSD forum, if you need some details for reference:
