Hi Archer,
Versions <B had a cache, versions B> use the /myth/tv as a direct record storage. What you watch is saved with a short auto expire (not short enough for me IMHO) so if you watch much tv it will be full most of the time deleteing as space is needed for a new show.
There is a setting in the utilities/setup > setup > general > about 3rd page that has an adjustment, top line. Exactly what it does, I don't know.
With 'B7, most likely you have a bunch of .nuv files in the /myth/tv, you can safely delete them. It was a carry over from mythlink.sh in the <B series which allowed proper housekeeping.
You may fix that feature by editing :
#nano -w /usr/local/bin/mythlink.sh
and adding #
#print "Creating missing file $mythpath/$ofn\n";
# open ($dfile,">$mythpath/$ofn") || die("Could not open txt file. $!");
# print $dfile "Creating dummy file for $title $subtitle \l";
# close ($dfile);
# next;
What those lines do is make a dummy file if a title is in the db however, no recording is available. With out that file, in the version A, you could not delete the entry. With the B7, the recordings are .mpg so therefore the script thinks all recordings are missing and you will get a dummy file, one for each show watched.
The good news is that cesman with his wisdom, removed that no longer needed feature in R5C7
The original post did not specify their version of KM, so therefore it was a generic response. One additional occurance is that it could also generate large error logs and fill up the / partition. Some have also reported large mysql logs.
Check the wiki and a good careful search of the forum should give you most of the details and cures.
