Presence of some number of different phonon modes is common feature of lattices  in ternary as well as quaternary solid solutions and in structures with double (DQW) and multi quantum wells (MQW). This peculiarity is rearranged on electron transport in such systems as diversification of electron-phonon interaction and is appeared in Magnetophonon Resonance (MPR) [1] as additional series of peaks what was observed in CdHgTe [2,3], ZnCdHgTe [4] and MnCdHgTe [5]. In case of MPR in MQW and super-lattices except additional series [6] was observed the subtle structure of peaks  too [7].  In this paper are presented and analyze new data of MPR obtained in strong pulse magnetic fields for DQWs based on the GaAs/AlGaAs and  InGaAs/InAlAs hetero-structures [8]. The analysis  is based on correct calculation of the Landau level energies in QWs and on the conception of deformed tetrahedral basic cells of phonon spectra in solid solutions [9]. The subtle structure of the MPR peaks is explained without participation of the interface phonons or confined phonons.
