there's always an empty file created in liveTV, it's the dummy
recording. nothing to worry about. It will be deleted the next time
the auto-expire is run (it wasn't always deleted due to an issue Ive
resolved in 6e5d8cff72fb116d707d9cb165aec023c7fd3b27)

what playback issue are you having?

-v file --loglevel=debug on the backend would show which file are
created and when written to.
I recommend commenting in libs/libmythbase/threadedfilewriter.cpp
uint ThreadedFileWriter::Write(const void *data, uint count)

line #302:
    LOG(VB_FILE, LOG_DEBUG, LOC + QString("Write(*, %1) total %2 cnt %3")
            .arg(count,4).arg(totalBufferUse).arg(writeBuffers.size()));

that's very verbose with mpegts streams as it shows every 188 bytes written.
and ultimately adds very little useful information
