I have a 500 GB hard-disk, formatted by mistake

I tried some other software and could recover the data, but missing few very important file-types i.e rmvb ( Video), iso ( Disk image) and nrg (Nero Disk image).
can someone help me getting .xml file written for these data types?
Thanks for your time and help.

Haresh
PS: In options we can select or deselect the file type to be recovered, but there are few file types which we can not deselect, is there any way to do that, so i can only search for rmvb, iso and nrg types.
