We had this issue in the past, too, for our "EuroLST" project
(gap-filling of all LST maps for Europe, see
http://gis.cri.fmach.it/eurolst/).
Solved since then, see below.

You may take a look at
http://pymodis.fem-environment.eu/

pyModis >= 1.0 comes with fast GDAL support (way faster than MRT).

The details of the gdalwarp usage you find in the source code here:

Hope this helps,
Markus
