From the manufacturer's website: "Replay A/V is the only software that combines Stream
Capture, Audio Recording and an Enhanced Podcast
Client in one easy-to-use interface."
The most important feature: "Stream Capture lets
you save the bits and bytes of streaming audio and video directly
from the internet. Replay A/V is the only software that supports
Windows Media, Real, Flash, QuickTime
and Shoutcast streams. The benefits of this technology are
enormous - you can capture multiple streams simultaneously (10
or more is doable with most broadband connections), and you get
perfect reproduction at the smallest possible size. Plus, unlike
other audio capture programs, no background noises creep into your
recordings, and the sound card remains free for normal use."
