Yeah, you can forbid the program and/or the user to move the
window with

  Style myxv FixedUSPosition, FixedPPosition

(US for user movement, P for program movement).  You may want to add

  Style myxv FixedUSSize, FixedPSize

If that does not fix it, xv is creating a new window with a
different name.  You need to figure out the name and add the
apropriate styles.  With

  bugopts explainwindowplacement on

fvwm prints a detailed explanation of where it places a new window
and why.  Also try FvwmIdent on the window in question to figure
out its class and resource name (both can be used in styles).
