Very strange! I have used this clip before I have it in my project and can double click and play it on my Pp monitor, where it looks and sounds fine. However, the moment I drag it to the time-line this introduces problems, a couple of apparent video glitches, a loss of sync and the audio cuts before the end, there is also a marked loss of audio level and quality..... Apart from that it's fine...

What could that be about? it's the first time I've seen this fault. The clip has always run in Pp 1.5 Much as I would like to, upgrading to CS5 is out of the question at the moment so all suggestions would be very much appreciated.
