[Qgis-user] On the fly projection

[Siki Zoltan]

Hi List,

I have trouble with on the fly projection from epsg:4326 to epsg:23700.
When I create a custom projection and test it in QGIS custom 
projection window I get the correct values
E.g 47d 19d -> 183979.50 646390.96
parameters: +proj=somerc +lat_0=47.14439372222222 +lon_0=19.04857177777778 
+k_0=0.99993 +x_0=650000 +y_0=200000 +ellps=GRS67 
+towgs84=52.17,-71.82,-14.9,0,0,0,0 +units=m +no_defs

But when I have the same point in a shape file and turning on on the fly 
reprojection with EPSG:23700,
I get 646306.05 183949.62, and it is the same if I ommit the towgs84 
parameters, more than 90 meters difference.
Where can I change the projection definition permanently in QGIS?
I changed the epsg file of proj but it doesn't help.

Trying it on QGIS 1.6 Linux and XP, I get the same result.

Thank
Zoltan
