Wife had recently noticed that the playback volume on recordings was lower than when watching the same channel live. Investigated a bit and noticed the audio stream was different. Example being BBC 1 HD live showed audio stream as ff-ac3, 32 bits, 48000 Hz. When I record the same channel and playback the audio stream changes to pt-ac3, 8 bits, 48000 Hz. I presume its the drop from 32 to 8 that is lowering the audio quality and making it sound lower.
Recording stream profile is 'pass' and I haven't changed any codec settings so can't quite work out why it plays live OK but then only records at 8 Bit. Also not sure why ff-ac3 changes to pt-ac3.
