Tvix 4100SH Firmware Upgrade Over NFS

This isn't so much a tutorial, but more of a "heads up" to all Tvix M-4100SH owners out there.  The other night I was watching the documentary "The Soviet Story" and naturally there was subtitles, and naturally my Tvix was being a pain and refusing to play them!  I knew there had been some firmware updates since I did my last one, but wasn't too eager to drag out a USB key and start fiddling with my Tvix box and downloading the firmware to a key, transferring it over, etc.  Instead I dumped the latest beta firmware (1.7.11) onto my NFS Server and took the leap in upgrading my box over NFS.  This seemed like a signficiant risk as I assumed somewhere in the upgrade process the nfs client service on the Tvix box will become disabled and the whole process will fail. Not the case! The firmware upgrade went perfectly smooth over nfs; too bad the manual doesn't hint towards this option.
