Thinking about this, it has to be something to do with the import process PP generates Peak files and conforms them...
What could be occuring?

Report back with the codec details of your file, use the programs below
For PC http://www.headbands.com/gspot/ or http://mediainfo.sourceforge.net/en
For Mac http://mediainfo.massanti.com/
Once you know exactly what it is you are editing, report back with that information...
and your project setting, and if there is a red line above the video in the timeline,
which indicates a mismatch between video and project
Thanks Bill, checked that out and didn't help unfortunately
I have done as requested and ran GSpot, not quite sure what results you would be most interested in so I have provided the ones below, let me know if you need anything else for a possible solution.
File length - Correct
Compatibility Note: DV Type 1 AVI
DV Audio/Video: 3.96GB (99.72%)
AVI Overhead: 11.3MB (0.28%)
Codec field is Blank
Info field in Blank
Stat - Codec(s) Installed
Codec - dvsd
Name - DVC/DV Video
Status - Codec installed
Under Proposed Codec Solutions and Tests on the MS A/A tab this error came back
Rendering failed. Following is the error reported by Direct Show:
There is also a bunch of stuff under the GSpot tab (Vid/Aud) but to much to ypre out and couldn't see a away to copy and paste here.
I am using standard Def PAL (576x720) AVI file
32000Hz - 16 Bit Stereo
There is NO red line in either audio or video.
Thanks for your continued support
I have been working on this problem all morning and you had certainly gotten me to thinking about the problem in more detail. The guides you suggested were really helpful but alas have not allowed me to solve the issue.
However I have done some more testing as I was very curiousas to why GSpot was not showing any Codec under the Audio section for my clips.
I have at least found a solution to my glitchy footage and it comes down to what settings I have on my Z5 and MRC1 unit. After numerous tests I have disocered that recording to the unit in AVI format whilst the Camera is set to DVSP NS32k results in the very glitchy soundtrack.
When I set my Camera to NS48k (still in DVSP and AVI on the MRC1) the playback in PP is settled and clean howver out of interest I ran it through GSpot again and it still gave no audio codec name.
I also found that the footage is ok in PP with the NS32k setting if I change the file format on the MRC1 to RAWDV.
I then went on to test HDV and as the Audio is fixed at NS48k it was only a test as to recording to the MRC1 in file format AVI or RAW DV.
Suprisingly although the audio appears clean, each instance results in the last 5 frames of audio dissapearing.
This I can live with I guess.
I am still very interested in understanding and finding a solution to the main problem I had. Why is the audio on my NS32k, AVI file so glitchy in Premier Pro and why is GSpot not showing and Codec in the Audio box?
I hope that anyone having similar issues can at least see what can be done to fix the issue in the most part.
If I have learnt anything by this headache it is that avoid the HYBRID and either use tape or Solid State... LOL

One major problem that I can see is your DV Type 1 AVI format. Convert it to Type 2. Type 1 has interleaved audio and video which is the reason your audio shows up blank in Gspot. Type 2 AVI should solve your problem.
As an FYI, DV audio at 16 bit is defined specifically at 48K only. You can have 32K audio in a DV file, but only at 12 bit.
I wonder if this bears any relevance.
I think it does. The Z5 Audio option are:
FS32K - records in 12 bit mode (2 stereo sounds). Select this setting for DV/DVCAM
This is the audio setting that plays havoc with PP on import for audio.
FS48k - records in 16 bit mode (1 stereo sound in high quality).
This etting seems to be ok with the AVI file the Unit records in.
Why the 12 bit mode (my preference) plays so poorly is what I am trying to figure out but with no luck.
Can't help with that. But why would you prefer inferior audio?
16 bit 48K is the norm. I recommend just going with it.
The other oddball item in GSpot is the dvsd codec. Take look at this posting. This was the opposite usage, but here may be a clue for you, "Note that Microsoft’s DVSD decoder is DirectShow-only (like its motion jpeg decoder), so you can’t do editing with it in a program like VirtualDub (or a program that uses Video for Windows as opposed to DirectShow)". I am not sure if this applies to your case or not but you probably need to do more research on dvsd.
I have prefered 12bit mainly due to the way it shows up in PP. The spikes are nicely there for syncing where as with
16bit the audio pattern doesn't show as well. May seem daft but it been a quirk of mine for a while as I am syncing up AV all the time.
The other oddball item in GSpot is the dvsd codec.
That's actually quite normal. Gspot shows that for all DV video, and it works perfectly fine in any app I've ever tried. I find the info in the linked post to be unreliable.
