It's not hard to convert to anamorphic especially if you already have the discs like the ones TR47 has. One way is to use DVD2AVI to convert back to AVI and use an encoder like TMPENGEnc Plus to convert to 16:9. The only thing is that you can't get any additional because the files have previously been captured and encoded previously. If there is no problems with the source, you shouldn't have any quality problems anyway.
