[Wine] Gom player help

[Finlay]

Hi all, 
I have the problem that I can't save the position of the asf video that I have seen until now with Gom Media Player: when I open a very big asf, even if  it is on the PC hard disk, it is like opening a buffer that prevent the vision from the point where i left the video. 
With Avi or Mpg I haven't this problem; I don't see this buffer effect. 
Does anyone of you know how to modifiy the asf file to avoid the buffer effect? Or how to convert it to .avi without quality loss and limitated dimension?
Or, more simply, does a Gom player setting exists to avoid this problem? 
Thank all of you
