I don't see that behavior on my machine, neither via xvideo nor via v4l
plugin ...

saa7134 correctly reports 720 as maxwidth (when in PAL mode).

The only thing you'll have to care about is that the max size reported
by the driver isn't fixed but depends on the current tv norm, i.e. if
you switch the driver into NTSC mode the maxsize reported by VIDIOGCAP
will change as well.  I think kdetv does that correctly through, while
checking the code I've seen it does first set the norm and then check
the max sizes ...
