[mythtv-users] What NOT to do to your Myth box...

[Michael Miyabara-McCaskey]

After you have finished the what appears to be a monumental set of tasks
to get the DVDs authored...

How to you access them? Do you just store them on the shelf?

I myself was hoping for a solution to use cheap off the shelf Sony DVD
jukebox - 400 DVD (1.56TB capacity - for $300)... that could be fed into
the Myth backend, somehow... but havent seen any response on a previous
thread.

Many have also mentioned doing RAID, but this only helps in the case of
HDD failures... As noted by this thread, there are plenty of ways to
accidently delete or corrupt your data.

Thoughts?
