The watermarking isn't something you can hear, but it is a signal that is embedded in the file.... It should be a non-issue as far as quality is concerned.
Ah. I completely misunderstood. I'm used to dealing with sites like Megatraxx that loops "preview" in all of their sample tracks until you purchase the final copy from them. If it's just going to be an embedded, low signal, that shouldn't be a problem. Unfortunately, I'm probably going to look like a jerk to the person at TVPMM who reads my response now, having found this out. (I assure you that looking like a jerk/being a jerk to people on the Internet is never my intention, no matter how my posts read. I always try to be as respectful as possible.)
The only way to manually accumulate cues is by using SoundForge Audio Studio to record the audio and create our own mp3 files without lifting directly from the site.
I always said that I would pay to hear the classic TPIR cues in the clear, and I stand by that remark. It's even tougher for me as a college student to find a place in my budget for this, but I'm still going to do it anyway. However, it's frustrating knowing that I may not have had to pay to hear these cues if people were a little bit more responsible with the material that TVPMM has given us for free.
I know it's none of my business what you do in the privacy of your own home with your own computer equipment, but I'd recommend not lifting files in any way. IP's will be tracked, meaning people can (and probably will) be banned, regardless of payment status. I wouldn't want you or anyone else to get the banhammer, so respect the privilege and enjoy streaming the cues from the website.
