Cheating yourself and the end user.
Radio options is a way of only 1 of each of the other.
  (a) OR (b) OR (c) and not (a) maybe (b) OR (c)
 
Check box is a selection from a collection of several choises AND/OR nothing.

 
The most correct solution is (in my view):

+-- Set Extension --------------------
| [] Check box: Use custom extension
|   -- custom ----
|  () radio : save as *.gif
|  () radio : save as *.jpg
|  () radio : save as *.bmp
+-------------------------------------

Or use a selectbox with 4 rows and the first as empty
  +----------------+---+
  | [empty]        | V |  or 'Use orginal extension'
  +----------------+---+
  | save as *.gif      |
  | save as *.jpg      |
  | save as *.bmp      |
  +--------------------+

Once you have forgotten the hidden radio as unlogical control
to do something logical as a yes/no question with the check box.

It is the fault of the unlogical control preset in VB and HTML
you could have all radios conditions as 'off'

I have a problem with a local website using this misbehaviour in html
It can plays media with WMP ( as hidden), Real (as option) or Qtime (as option).
Once I did try with Real and it did not work.
No way to use WMP as default player again. Why?
