RTMPdump and rtmpsrv are both great programs

I was just wondering has anyone found an easy way to pick the QUALITY of the downloaded stream?

For example Hulu offers 480p, 360p, and 288p
rtmpsrv seems to only want to download the 360p

The best workaround I have found is doing a dump of the browser then parsing the URL for the higher quality stream, but this is a huge pain
