Fixed bug in dvbapi not releasing used descramblers in stapi, coolapi and gxapi boxes
Increased MAX_STREAM_INDICES back to 32 (it must be equal to MAX_STREAM_PIDS)
Modified the get_emm_filter_adv() function to accept more arguments

OTHER:

New in emu


    Added a new method for matching powervu keys *
