today, i see a guide and i am very interested in subtitle adjusting and editing, and i own the  platinum version of xilisoft DVD ripper , never think about the ultimate version. actually, they have email me about spent $19 to upgrade to the ultimate, but i did not pay any attention about the new functions. recently i DIY some video clips, and need to add watermark and adjust subtitle.  this one boasts it can do these so.
i have downloaded and tried, hum, i want to say it is perfect! if u have the needs as me go to see it is details. and heres the guide written by Phoebe Cho   http://www.tucows.com/article/2128
