It only works without X?  That really doesn't make any sense to me.  I
can't think of any reason a capture card would stop working when X
starts.

fps=50?  The F in fps means frames not fields, so that should be fps=25.
 You're just wasting CPU time doing that, AFAIK.

What?  I think you can safely assume (PAL) TV is always going to be
interlaced.
