Indeed I am using ext3 on a Mandriva 2006 box. If I look at the partition information I see the following:
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hda1 8840140 2607112 5783968 32% /
/dev/hda7 20560436 6800040 12715984 35% /opt <---- storage of recorder data
And in Mythfrontend:
Disk usage on server:
20 GB total, 7.5 GB used, 12 GB (or 62%)...
So it seems that both Mythfrontend and df are more or less in agreement. Also when I start the backend it shows the following in the log file: 2006-08-10 09:41:38.161 AutoExpire: Required Free Space: 3.1 GB w/freq: 10 min
So, somehow Myth calculates with 3.1 GB/10 minutes of video? Even though the pixels and bitrate on the "default" recording profile are set in such a way that in reality it is 250 MB/10 minutes. This is just not right!
And also this response does not really answer the question I have: How does MythTV v0.19 decide when to delete files. What are the space calculation rules? Can anybody explain these rules? And then the logical next step: How can one influence these rules?
I did find out that MythTV also deletes a recording which is specifically marked "no auto-expire", which I set because I really wanted to keep it.
Oh, and what is this "root reservation" thingie?

What filesystem are you using? How big is your partition? Where
are you reading the free-space figure (`df` or the mythfrontend
If you're using ext2/3 then you may be running into the root
