clone dvd makes 5,38gb instead of 4,7gb

[realas]

after decrypting, video_ts folder is about 7,71 gb. with clone dvd v3.0 i set 4,7gb disc and "compress to fit into one blank disc". removed unwanted langugaes and subtitles.
in the next step program shows "disc #1 input size (7326mb), output size (4489mb)". looks like everything is ok.but.
but, after long long operation (about 5 hrs), output file is 5.38gb. what's wrong? maybe older version of clone dvd doesn't makes such things?

Try using "DVD Shrink" (freeware) as an alternative instead of "Clone DVD".
