I've tried many ways to capture using
rtmpdump using both rtmpsrv and rtmpsuck and using
RTMPexplorer with the SiriusXM feeds without any luck.
I tried
GetFLV with limited success. It doesn't always capture properly and when it does it's not automatic, meaning I can't set a timer to record. It doesn't defeat the player's 90 minute (or earlier) timeout issue. And at $60 it's fairly expensive compared to what Pulsar and Audio Hijacker (both from Rogue Amoeba) offered for Mac users at nearly half the cost.
If
Replay AV would update that would be wonderful. Until then I'll continue my quest for that near-perfect software solution.
