thanks loads for the tips folks!
the H264 playback issue makes sense
i did some test exports to DV-DVCPRO-NTSC in the meantime (following another 
friend's advice), progressive & with deinterlacing
& they played back aok on the mac, in quicktime, with no interlacing
I'll give H264 a lash as well
much appreciated!
cheers moira

Try playing your files on VLC player, it's freeware and may work just fine. I 
wouldn't recommend h.264 since it's heavily compressed.
