Your sample command line should do what you request. The synopsis of
MEncoder looks like:


mencoder <common options> file1 <options for file1> file2 <options for file2>

Now, maybe MEncoder doesn't honner seeking options as you'd like it
too, but that's a shortcoming of MEncoder WRT the input file format
(for example, precise seeking doesn't work well with DVDs and MPEG2
files.... and doesn't work at all with flv files).

Hope that helps
