If you like to evaluate the decoder filters, we recommend downloading our MainConcept ShowCase software player as 32-bit and 64-bit version. This application includes all decoders we offer as MainConcept Decoder Packs as demo versions. It only adds a watermark to the video during playback and has an audio limitation of 30 seconds for some audio decoders.
