Bigblunt … i have the same isse with mine.
I use wireless connectivity, using a Belkin wireless modem/router, and have a Belkin wireless adapter in the WD TV Live Hub.
On my Windows 7 laptop I have set the WDTVLIVEHUB as a network drive and I can browse and manage folders, no worries.
I can copy small files (for eg, an album or 2’s worth of mp3s), but if I try and copy a 1.3Gb avi file across it gets about half way in at around 1.3Mb/sec, and then loses connection to the drive and never reconnects/resumes.
So, wrt to ‘wired’ operations.
It is 100% not feasible for me to connect my laptop to my router to my Live Hub, so lets immediately rule that out (opposite sides of the house).
If I connect the laptop directly to the Live Hub via an ethernet cable and use the clunky WORKAROUND of setting static IP addresses for TCP/IP4 port and the Live Hub, I can get seamless copying (at 16Mb/sec). I hate this route though, because its such a pain to configure.
Suggestions, anyone? Maybe I am missing something fundamental here (I hope so!) but right now my experience of hard copying files from my laptop to the Hub is painful and awkward.
