Slow running Pinnacle Studio 15

[Jeffrey]

Studio edited footage from my old Sony HD camera fine. I now have a Cannon videocam and Studio cannot cope with the AVCHD footage it produces. It is unbearably slow.
My computer: Intel core i5 - 2500 K CPU at 3-30 GHz. NVIDEA GeForce GT 430. Memory 8 Gb. Windows 7 64 bit.
Any advise would be gratefully accepted.

did you do any research before buying pinnacle ?

it has the worst history of any editing program going ! do a search for "problems with pinnacle software"

only advice i can give is get rid of it.

Sorry to come across so negative but it annoys me that pinnacle have been getting away with releasing junk for years.
