a friend of mine got married and the video guy gave him a VCD and a DVD copy of the wedding.now the vcd is the regular vcd which plays well in vcd players. however, the idiot seems to have mangled with the dvd where there is a dat file which plays only on computer.i guess its the same dat format which is used on VCDs. how do i get it converted into a dvd which plays on regular dvd players....
