The Beta tape unfortunately suffers a lot of background noise. The noise level goes up immediately after the CBS/Fox intro and the file begins, gets worse somewhere in the middle and down a bit the rest of the film. I have no idea if this is from the ravages of time, exposure to magnetic fields or just really poor mastering. I dug out some other Hi-Fi tapes I have just make sure the deck was working properly. It is.
However, I think the audio for the phone number scenes can be cleaned up. Here’s a sample, and this is pretty good compared to other parts of the film.

On a side note, did the Mission Impossible theme music always seem to start a second late into the panty raid seqeunce? This occurs around a reel change and may simply be a video mastering error.
The LD is pretty nice sounding, I’m not noticing what you’re describing from the beta. The LD has no chapter stops, so I’m on my third capture of the film but I’ve been able to capture the deleted scene 7 times (thanks to rewind). Hopefully I’ll be able to median the caps and get it as close to the master used as possible. Here’s hoping it does turn out to be a good year!
