How to make a duplicate copy in 5045 HD?

In 5045, how can I make another copy of an existing recording in the Hard Disc to the Hard Disc itself? In other words, how I can duplicate an existing recording in the HD? I know I can copy to a DVD first and then copy it back to HDD. Is this the only way? If so, won’t the quality decrease?

Please help. Thanks.

Only way is to goto a disc first.

The quality will not decrease as all you are doing is taking a digital copy from the HDD to the DVD and back again, there is no recoding going on in that process.
