sound level very low on some iptv films

[cutain]

hi all I am rather deaf in left ear ,and use cordless headphones as I do a lot of late night viewing.

watching iptv film gravity I could not hear the speech at a loud enough level (regardless of sb600 volume or tv volume settings) to enjoy the film.

on the other hand wolf creek 2 the sound output was much louder.

is there something I might have missed to increase iptv sound output.

happy nrw year to all

thank you

the sound on the spider as default is set low ...after any spider factory reset or patch loading volume needs to be turned up on spider using spider remote
i am saying this incase after a factory or patch load...you may have forgot turn up volume on spider
although like you state...some iptv items do differ in sound levels

thanks spider volume is at max, ill just have to choose films where sound level is a bit higher.
