I know that some people here use Sony DVD Architect Studio and others may be considering it.
Our newspaper today has a Frys Electronics ad for it that says net zero price. However $20 of the rebates are an upgrade rebate so it might actually be net $20 for a new purchase. On frys.com, there is also a price reduction that is also potentially zero and it says competitive upgrade rebate.
This appears to be version 4 - the sony site shows version 4.5 if you buy there (see https://www.sonycreativesoftware.com/sh ... 463&disp=1).
I don't know the difference between 4 and 4.5 - perhaps someone else does.
If interested, please do check the details carefully.
