Re: PT is lagging
Sounds like the file is heavily compressed, maybe something like h.264? Codecs that require a lot of CPU to decompress make life difficult for Pro Tools. If you have Quicktime Pro, export the file to DV and you should notice a big difference in performance albeit the file will be much much bigger.
Cheers
