Say for example this video mms://wmsvidzone.ld.mediawave.co.uk/secvidzone/0011161.wmv
If I play it in Windows Media Player and the highest bitrate is selected, only 22MB are transeferred. But if I record it, I get a 61MB file that includes 7 bit rates (from 28 Kbbp to 715 Kbps). Btw, I can extract the desired clip with Windows Media Stream Editor (wich would solve the diskpace issue). My problem is when it comes to live streams and the total bitrate is higher than my connection speed: I can play them, but if I try to record them there's of course loss of packets.
I downloaded the clip with WM Recorder, Replay A/V, NetTransport using the highest bit-rate possible. I got 62MB file.

There are no media stream recorders that can record all the bitrates of live stream simultaneously. Any stream recorder as well as streaming media player negotiates the bit-rate before starting to receive data from the streaming server.

There must be some problem with your evaluations of traffic transferred.


Obviously live streams are much harder to get whether you wanna watch them or record them. No one has offered a 100% reliable live stream distribution method yet.

The following FAQ may help you with poor quality of live stream recordings:
