Being the wrong side of 65 so not yet retired ;0)
The Windows version of iTunes can automatically transcode DRM-free WMA (including version 9) files to other audio formats, but does not support playback of WMA files and will not transcode DRM protected WMA files.
iTunes 10 can currently read, write and convert between MP3, AIFF, WAV, MPEG-4, AAC and Apple Lossless (.m4a).
if I copy and paste a track into my music files will this fall within the formats accepted by Moviez?
Yes provided the track is AAC, MP3, Wav or WMA Formats.
