Have you ever noticed when placing a call to a company's customer service line there is usually an automated message saying the call may be recorded? Once that message plays and you remain on the line, you are giving implied consent to be recorded. If a state requires two party consent that does not mean nothing can be recorded, just that both parties need to know and agree.
Video/audio shops can be conducted in two party states as long as employees have given consent to be recorded. This can be done as part of their initial employment contract or at a later date. When in doubt it is perfectly reasonable to ask the MSC if the employees have given consent to be audio recorded and to see the documentation. In two party states only the client's shops can be audio or video. Any competitor shop would have to be written only as the client will not have documentation from the employees of a competitor.
As to using the DVR for your personal notes, some have adjusted the mic to only pick up their own voices and can piece together pertinent information such as timing that way.
Equal rights for others does not mean fewer rights for you. It's not pie.
