How is this? ( Codecs Pack )

Hello friends, I went to the Grass Valley Website and downloaded the Edius Codec Option 6.52   ( Code Pack )
that they got for download, and seems to work good, but when I switched to my Windows 7 64b to import
a small video with this codec, Premiere Pro CS5.5 cant display the video, however you can see
the video on The Windows Files Browser, how is this?

Thanks       Orlando
