I have a Synology NAS and was using it to record direct from MythTV to the
NAS.  I ended up changing it to an old drive I had laying around after a
few weeks of doing this.

It worked fine, I was just concerned that I would run out of drive space
for the 'Live TV' folder.  What I did was direct Live TV to the old drive
mount point and store the recordings and everything else on the NAS mount
point.  Synology is shared to the server with NFS.

The only time I have had speed issues was when watching Live TV across
subnets within the local house.  I had my HDHR on one subnet, MythTV on
another, and the workstation on the third.  When doing this, I would get
pixelation between Myth Backend and the HDHR.  Moving the HDHR to the same
subnet resolved this issue.  All networking is gigabit, but I have a
feeling that the NIC on the backend couldn't keep up with everything.  I am
running vmware esxi on it and everything was passing through the single NIC.
