Crackling sound problems with Spiderman2 and I-Robot

Hello,
I’ve been copying DVDs to my hard drive for a while now using AnyDVD and CloneDVD2 (I have the latest versions now) and have found some issues with these two films.
Whenever a big moment sound effect happens it’s rendered ok, but with alot of crackling. I have updated everything I can think of, but to no avail.
I have also succesfully copied other new films such as Troy, Wonderful days, with no problems whatsoever.

Any ideas please?

As neither AnyDVD, nor CloneDVD modify the sound streams, this is highly unlikely… Just in case: Using NVIDIA IDE Busmaster drivers?

I know it sounds unlikely, I couldn’t believe it myself …
to answer your question, no I am using MSI Neo 2 Mobo (P4), Intel Bus master.

still baffled to be honest… another new DVD which worked without problems : Shrek2.

I thought this might be purely an audio codec issue, but since i’ve completely stripped those and readded them (K-Lite code pack), I ruled that idea out, and if it were a codec issue then surely i’d have the same problem with anything I played, right?

Thanks for any continued ideas
