Purchased Playback a couple of days ago and was very happy with the ease of setup and use. I do have a problem with movie (m4v from DVD created with handbrake with universal preset) every 10 minutes or so I get dreaded ps3 error 80710723 (I think it is) timeout error.

Setup is iMac (2011) Lion OS X 10.7.2, linksys E3200. iMac and ps3 are on wireless network. Ps3 and iMac on static IPs, ps3 in DMZ (read this might fix it but it didn't. Ps3 reports 8mbps for Internet speed test.

I suspected that maybe the Mac was turning off HDD so I tried changing power saving settings. This still didn't work. Is it simply that streaming m4v over wireless is not doable? I can and will run a wire but if that won't work then I'd rather not waste the time doing it as it will be kind of a major undertaking.

Thanks for any help!
