Hey shock.. I understand you very well. Been searching the net for a fix the last few days.
Just bought an 4th gen 2TB Time Capsule to extend my 5ghz Wifi-n Network to my mediabox running XBMC.
Plan was to store all my movies on the TC and stream them via ethernet.
I'm very surprised to see the results!
I can successfully stream a 1080p DTS mkv's via 10m ethernet from my iMac, running SmbUP (SMB v1.0), since v2.0 in Mavericks is not working too well.
I find NO WAY to successfully stream the same file directly from the Time Capsule, here a 0.5m cable.
With SMB I get freezes/buffering every few minutes (even with the new
buffersettings in Gotham)
With AFP it plays nicer but here I get total system freezes after pause->play which require reboots.
I've now read that the SMB implementation on the Time Capsule (and probably AE) is crap.
And the same goes for AFP implementation on XBMC
Now I'm trying to figure out if I should sell my TC and buy an USB-wifi dongle for my mediabox + an external USB HDD for it..
Cheers,
Seb
