considering upgrade to MS V4.000, question

[Ronald Moon]

Am presently running MS V 2.613 which has worked fine for CD-G copying/editing. Using Plextor PX-716 UF burner. I recently purchased a CAVS DVD 203G karaoke player with a number of MP3-G tracks. I will want to convert (edit) some of these tracks to CD-G and burn them to disks.
1. Is this possible with the new program and using the indicated burner? 2. Will the V2.613 program upgrade successfully to the V.4.000 program? 3. Will the new program allow reverse conversions (CD-G to MP3-G)?
