sorry if I could not go through all the 4 pages of information but capturing cam4.com streams is real easy I find.

1. get URL Snooper 2 and have it running on "search all" in advanced mode.
   
2. go to cam4 and click on any cam you like, you don't need to be logged in for this. for this example let's say we are on abc123's cam.
   
3. now check url snooper 2 for the real long either yrtmp or xrtmp URL like this one:
   

   yrtmp://85.17.127.81/cam4-origin29/_definst_/streams/90d6b3d9-b77f-4a8e-98eb-4a632324d9b5?e17228c3dc81384a39f82fd1e726ab28

   if the real long URL with the question mark in the middle does not come up straight away refresh the page and leave url snooper 2 running untill you get the real long URL, the other simple rtmp URLs won't do!
   
   note I am using the noscript addon in ff and only allow cam4.com and flush the cache with the clear cache addon if I don't get it at first, but I am not sure if that makes a difference. sometimes you get the long URL straight away sometimes you have to refresh the page a couple of times or quickly go to another broadcaster and come back and you will have it straight away.
   
4. pop that stream URL into this command line:
   
   

   rtmpdump -r "PUT THE REAL LONG yrtmp or xrtmp URL IN HERE" −v -o abc123.flv

5. done. you can now see other cams and snoop other yrtmp or xrtmp streams while it is recording abc123's cam. it will let you record as many cams as you like for as long as they broadcast. the file output is in flv format. you can play that with media player classic or any flv player, think vlc, mplayer and the likes will play it effortlessly.

hope this helps.

edit: rtmpdump will give you a warning but it will record the live stream perfectly, when ppl use hd cams you get the hd stream, when people use higher res cams you get the higher res stream no matter what resolution is show through the site, it is like you are directly recording off their cam without cam4.com in the middle actually.

if you have missing timestamps on the flv file look here some useful FLV tools:

• FLV MetaData Injector - Adds meta info to your Flash Video files
  
• FLV Player - play FLV files with freeware FLV players
  
• in case you want to do stuff with the flv files in virtualdub have a look here:
  FLVExtract - Extracts video and audio from FLV files without decompressing or recompressing

sidenote:
i think cam4.com was good for some time but now there is just boring people on there but that is just my opinion.
