Although both .rxs and .cif file types come from Roxio software, it is unlikely some kind of rxs to cif conversion is possible. This is due the fact that both file types serve completely different purpose and do not contain any similar data that could be exported / converted.
This conversion entry was verified by us and conversion was flagged as wrong or not possible.
Usually this happens when the conversion would try to convert different types of data between each other, such as audio to image, or it is not possible because incompatibility between programs, caused by closed file formats, very limited support etc.
If you find entry that you feel is flagged as bad wrongly, please tell us in the discussion below with as much as information as possible so we can fix it.
