Anomalies in 'required' and 'used' disc space for USB recording.

[Mooly01]

When I pick a program from the EPG to record as a timer event I am presented with the timer setting screen which always reports the space needed to record the deired program. 

The anomaly is this. A program may say it needs 5.5Gb free space and yet when the recording has finished and you look at the 'Recorded Titles List' I always see that the space used has been very much less.

These pictures give an example. 5.5Gb needed and yet the recorded program ends up as a reported 1gb used. Morse that is in the list actually 'required' 25Gb ! and yet comes in at 1.5Gb for a two hour plus film.

Further error creep into the pie chart showing used space. Currently it reports 48.7Gb free (its a 64Gb drive) and yet the four programs currently in the list report as 2.4Gb, 1.5Gb, 3.4Gb and 2.1Gb giving a total of 9.4Gb

 The numbers just dont add up any which way you look at it.
