Groom,

  Floating Weeds is by Ozu.  I believe you must be thinking of Floating Clouds, which is by Mikio Naruse.  Sadly, at this time, I've seen neither of the mentioned films.  All of Ozu's films are in the process of being released on DVD, I have been purchasing them as they become available.  I believe Criterion is working on releasing Floating Weeds sometime this year.  As for Naruse, no DVD's yet, to my knowledge.
