You may still not have the right mix of firmware and driver versions. 
I'm using a recent set of drivers from linuxtv.org plus 
dvb-fe-tda10048-1.0.fw plus NXP7164-2010-03-10.1.fw. I can't find any 
references to firmware for the TDA18271 tuner so I guess it doesn't need 
any.

Maybe try this to see what's loading at boot:
dmesg | grep -iE 'tda|saa|dvb|tv'

There is also a ton of debug info available with the saa7164 driver but 
it can burn up disk space very quickly if you turn on all the debug options.

They only get stored in the one livetv directory on my system. There are 
settings for "aging out" the livetv recordings in the frontend under 
Utilities/Setup>Setup>TV Settings>General. From recent use I can confirm 
that live recordings do not deleted before the max age time unless you 
run low on disk space.
