My point is you cannot just look at recording hours alone. Sky could record 480 hours of hd at a bitrate of only 5Mb/s. More hours of recording for a fixed hdd size and compression algorithm results in lower picture quality.

Now when you have different compression algorithms it just gets impossible to compare.

Which gives a higher quality video stream 10Mb/s mpeg4 or 24 Mb/s Mpeg2? I dont know the answer. If skys figures of 240 hours are true and Virgins figure of 99 hours are true, then these are the two things to compare.
