Using Rtmpsrv on Younow

[RTMPn00b]

First of, I'm pretty new to this so bear with me.

Basically, I know how to download broadcasts using rtmpdump, but it can take forever.

Rtmpsrv can download at a much faster rate. Thing is, it's very unstable, as in it has issues completing a download - in fact, it's seldom that it does. What occurs is that it gets stuck at a certain percentage and keeps repeating that particular chunk of the download, thus exponentially accumulating more bytes. I know that there's a resume command, although I'm not sure whether or not that would be the solution or how I would construct it into the existing command line.

Any help or guidance would be greatly appreciated,

Thanks.
