Good Morning

My 2 issues put short and simple are
1. What did I do wrong when changing the file owner and permissions recursively. and how do I fix this so I get it all correct?
2. How do I get my folders back to type:folder (recursively if possible as there is a lot of folder but I will do singly if its the only option).

Now the long version
System details
Xubutnu 12.10 with mythtv install ontop, RAID5 8TB, highend mobo, I7 chipset, 16GB memory, highend graphics (hardware not been an issue)

I have had a problem with mythtv videos library after moving most of my library around to clean things up.
After some time I realised it was a file permission problem (due to storing files on Windows machines, then coping them all back to mythtv machine. Also used 2TB portable HDD to copy files back and forth)

For those that ask I cannot back up as I have 7.5TB of videos. That is why files were spread across different machines during clean up
Before I started I had all the files for the kids store nicly under /var/lib/mythtv/videos/kids. The files we single file (single movie) or in folders (tv series) or folder groups single moives (eg disney, xmen, etc).

OK here is all the terminal stuff I did to fix the owner, group owner and file permissions problem
I am trying to recursive change all to owner:mythtv:RW, group:mythtv:RW, other:R only

Code:
chipppy@MythTV-Main:/var/lib/mythtv/videos/kids$ sudo chown mythtv:mythtv -R

chown: missing operand after `mythtv:mythtv'

Usage: chown [OPTION]... [OWNER][:[GROUP]] FILE...
  or: chown [OPTION]... --reference=RFILE FILE...
Change the owner and/or group of each FILE to OWNER and/or GROUP.
With --reference, change the owner and group of each FILE to those of RFILE.

  -c, --changes          like verbose but report only when a change is made
      --dereference      affect the referent of each symbolic link (this is
                         the default), rather than the symbolic link itself
  -h, --no-dereference affect each symbolic link instead of any referenced
                         file (useful only on systems that can change the
                         ownership of a symlink)
      --from=CURRENT_OWNER:CURRENT_GROUP
                         change the owner and/or group of each file only if
                         its current owner and/or group match those specified
                         here.  Either may be omitted, in which case a match
                         is not required for the omitted attribute
      --no-preserve-root  do not treat `/' specially (the default)
      --preserve-root    fail to operate recursively on `/'
  -f, --silent, --quiet  suppress most error messages
      --reference=RFILE  use RFILE's owner and group rather than
                         specifying OWNER:GROUP values
  -R, --recursive        operate on files and directories recursively
  -v, --verbose          output a diagnostic for every file processed

The following options modify how a hierarchy is traversed when the -R
option is also specified. If more than one is specified, only the final
one takes effect.

  -H if a command line argument is a symbolic link
                         to a directory, traverse it
  -L traverse every symbolic link to a directory
                         encountered
  -P do not traverse any symbolic links (default)

      --help display this help and exit
      --version output version information and exit

Owner is unchanged if missing. Group is unchanged if missing, but changed
to login group if implied by a `:' following a symbolic OWNER.
OWNER and GROUP may be numeric as well as symbolic.

Examples:
  chown root /u Change the owner of /u to "root".
  chown root:staff /u Likewise, but also change its group to "staff".
  chown -hR root /u Change the owner of /u and subfiles to "root".

chipppy@MythTV-Main:/var/lib/mythtv/videos$ sudo chmod 664 -R /var/lib/mythtv/videos/kids
chipppy@MythTV-Main:/var/lib/mythtv/videos$
What I have ended up with is

/kids owner:mythtv:RW group:mthtv:RW, other R only. Plus warning symbol below other box followed by 'the file permissions are inconsistent, you may not be able to work with files in this folder'.

When I drill into /kids the files and folder seem to be all there but (oh a but, that not good)

The single files are all the correct types (mpeg-4, iso, avi, etc) but have the permissions of owner:root (root):RW, group:root:RW, other RW.
When I try to open a file (play movie with both VLC and mplayer) they get a permission denied error

The folders are type:unknown and have permissions of owner:root (root):RW, group:root:RW, other RW.
As the folders are type unknown I cannot drill into then to check what has happen with the files.

This leaves me with 2 issues
1. What did I do wrong when changing the file owner and permissions recursively. and how do I fix this so I get it all correct?
2. How do I get my folders back to type:folder (recursively if possible as there is a lot of folder but I will do singly if its the only option).
