I have several Slingbox 350's, some with firmware v1.5.72, some with v1.5.85. The '350's with 1.5.85 perform much better. Specifically, they consistently connect in TCP mode, while the v1.5.72 boxes usually connect in SNATT or Relay and I see a lot of freezing, dropped connections and erratic bitrates. There are LOTS of complaints about this all over the web, which has me wondering why v1.5.85 was rolled back - It was a significant improvement! Is there a new version being released soon? What say you, Sling?
I miss my PRO-HD.
