So does this mean that without the fdatasync() calls it works ok as
it is in plain vanilla VDR (without any patch)?

What is the exact meaning of the "WriteStrategy" option?
Does it simply turn the fadvise stuff on/off, or is there more
magic behind it? I would prefer a version that works without this
option, because this is nothing a normal user would easily know
how to set.

So, if you can provide a patch against the latest VDR version that
still uses "#ifdef USE_FADVISE" to completely turn the fadvise
stuff off, and does _not_ introduce another setup option, I might
consider including it for the final version 1.4.
