It seems, that Power DVD 8 Ultra is able to do some more Audio Stream Formats, than the Version bundled with DVD Suite 7 Ultra. (DTS HD 5.1, while the DVD Suite 7 Ultra Version seems to be only capable of DTS HD 2 Channel) Now i'd like to know the following: Is it possible to simply use a Power DVD 8 Ultra Key with the PowerDVD 8 Version bundled with the Suite? If not: Is it at least possible to install two Versions of PowerDVD 8 with different License Keys on One Machine?
