Yes, you can go to the CloneDVDmobile program map and find the file Devices.ini. Open it and search for Motorola. There are 2 but use the 2:n SLVR. Change Res1=176x144 to what value you need and save. Start CloneDVDmobile and your new resolution will bee able to use. I will suggest what You make a small file first and see if your phone is able to play it.
Good Luck
