"file size...marked as 'B'" is because MythWeb shows you the file size 
using the most-appropriate units.  For a recording < 1024 bytes, the 
units would be bytes (B).  Since your recording has a size of 0 (because 
the file is non-existent), it shows the file size, but the 0 gets 
simplified out of the string, leaving just B.  All it's saying is it's a 
0-byte recording.

In general, any time mythbackend attempts to record a show and no data 
is written to disk /and/ no errors are shown in the mythbackend log, the 
problem is that the capture card or drivers provided absolutely no data 
for MythTV to write.  MythTV writes whatever data it's given, and if 
it's not given any, it doesn't write anything.  If the card/drivers 
don't tell MythTV there's an error, it doesn't write any errors to the log.

I seriously think that your EIT (or something else) is stomping over 
your capture cards and puts one or more of them into an invalid state 
where it won't work properly (and doesn't give any errors) until reset 
(where a reset could require--depending on card/driver--one or more of 
restarting mythfrontend, reloading the card drivers, or rebooting the 
system).  Therefore, this is likely just a symptom of the EIT issue on 
the ticket, or something else (outside of MythTV) using your cards 
incorrectly, or a problem with the hardware or drivers.
