I bought a Slingbox PRO and have it hooked to my DirecTV DVR. I'm really happy with the quality though it's hard to truly judge completely, at my LAN speed, because DirecTV is already so hideously compressed. At full speed at home the picture looks equal to the source. Hopefully soon I'll be able to test its HD capabilities. What I'm really surprised about, and pleased, is how good it streams to my laptop (G4 iBook) at work. I've got DSL service with DSLextreme, a 6000/768 line that I get near 5k/650 worth of performance out of, which is good for LA since SoCal has pretty crummy "high speed" internet choices. At work it's often difficult to view youtube.com or google video streams without stuttering and re-buffering but my Slingbox trucks along at a smooth 450-550 with video that looks cleaner than anything I've seen on youtube. I put it in the corner of my desktop in its quarter scale view but overlay graphics and subtitles even are still quite clear and readable. Sound quality is excellent. I'll be purchasing a Slingbox for my stepfather for his birthday. He's also a gadget head and will love the fact that he can stream to his handheld and laptop.
