Mythweb as always been a separate thing - even from source code, you
have to get it separately.  But if you installed the "mythtv"
metapackage that installs all the other MythTV packages automatically,
mythweb used to be installed.  Maybe that has changed in v30 and you
have to manually install mythweb now, as mythweb is deprecated.

A 5 GHz WiFi connection works fine when the frontend box has 802.11ac
WiFi, but I think an RPi only has 802.11n, which, depending on how
good the actual connection is, may not be fast enough.  The problem
with 5 GHz is that it does not go through walls nearly as well as 2.4
GHz, so where you have the RPi in relation to the WiFi access point
matters.  In your current (testing) location, it may not work well,
but it may be OK where you actually want to use it, if that is closer
to the AP or has fewer obstructions in between.

Closed captions "just work" for me using normal PC based frontends, so
I think you are probably right that it will be an RPi problem.  Since
I do not have an RPi, I do not think I can help much with that.

It would be easier if BE2 was upgraded to v30 also.  Then you could
just use the trick of swapping the config.xml files to get the
frontends to talk to either BE2 or BE3 until you have finally watched
or deleted all the recordings on BE2.  You might find that easier than
exporting all the recordings to BE3.

If you want to go ahead and export all the existing recordings from
BE2 to BE3, then you need to first decide how you are going to move
all the recording files to BE3.  How many recordings are there?  Do
you want to move the hard drive(s) with the recording files from BE2
to BE3?  That would probably be the easiest if there are lots of
recordings.  Otherwise, you would first need to ensure that BE3 has
enough space on its recording drives for all of BE2's recordings, plus
space for any new ones it will be making.  Then you would need to set
up network access (using SAMBA?) for BE2 to be able to write files to
BE3's recording drives.  Or you could temporarily install each BE2
recording drive on BE3 to move the recording files.  Or use an
external drive mount to do that.  I will need to know how this is
going to happen in order to do a custom version of mythexport for you.
Also, does BE2 have multiple recording file locations (multiple
directories in its recording storage groups)?  Does BE3 record to any
storage groups other than "Default"?  Does BE3 have multiple recording
drives, or only one?
