522 is eating up the available recording space??

[justthinking]

Somehow it seems like my 522 is eating up the available recording space.

I have only 1 show recorded and that show takes up about 1 hour of the recording space,
yet on the 522 DVR menu, it shows I have only 98 hours and 40 minutes available for recording.

If I delete all recorded events, 522 would show total available hours at 100 again,
but once I got something recorded, the total available hours would be short again.

Does anyone else has the similar situation?
Does anyone know where did the 20 minutes worth of recording time/space went?

nevermind, sorta figured out why...
I guess it all depend on the actual size of footage been recorded...
some shows uses higher bandwidth therefore takes up more space in the same amount of time as other shows...

Now you see why Tivo doesn't have a counter to show how much Hard Drive space you have
