Cypheros TS-Doctor is designed for recorded DVB transport stream to check for errors and, if possible, make it as compatible as it can to play it back without studdering or picture and sound delay. The program tries to change as little as possible in the original stream in order not to create additional incompatibilities. PAT and PMT be adjusted and non-existent PIDs deleted from the tables. The picture and sound streams will be analysed and displayed. Not needed streams will be deleted. The program has a detailed review of H264 and MPEG2 video streams and AC3 audio streams through CRC check
