Well, the way that it sould work (powerdvdswitcher) is this:
1. Install v.3730 (over the older one that you have or enything) .
2. Decompress the stuff that are included in the
.rar file someware.
3. Put the 2 folders (PDVD3319a and PDVD3730) in your C: drive (root) .
4. Put the file ''SWITCH_PDVD.cmd'' in your %programfiles%\Cyberlink folder (just outside of the Powerdvd folder) .
5. Put the ''SWITCH_PDVD.lnk'' link file wherever you want (usually desktop) .
Now you must be able to switch the 2 versions of PDVD with a doubleclick on the link file.
With this, you have the 3730 version as ment to be (original) and an altered 3319a. If you are having trouble, i 'll make a different one that switches both of them in the original form. Though, you have to install both of them and make some changes that i 'll write you.
For me, everything works fine with this one, but i am reading that some are having probs, so if you want i'll make the new one for you to try.
