Unexpected size download.

[Brian Penn]

Hi all,
I have notice that when I download some programs from the BBC via
get_iplayer they end up much smaller that expected.
For instance, using the recent drama "Page Eight" as an example ..

tvuser:~> get_iplayer --type TV Page\ Eight -i | grep modesize
modesizes:      default:
flashhd1=2344MB,flashhd2=2344MB,flashhigh1=583MB,flashhigh2=583MB,flashlow1=290MB,flashlow2=290MB,flashstd1=352MB,flashstd2=352MB,flashvhigh1=1099MB,flashvhigh2=1099MB,n95_wifi1=135MB,rtsphd1=2344MB,rtsphd2=2344MB,rtsphigh1=583MB,rtsphigh2=583MB,rtsplow1=290MB,rtsplow2=290MB,rtspstd1=352MB,rtspstd2=352MB,rtspvhigh1=1099MB,rtspvhigh2=1099MB
tvuser:~>

So i am expecting a 2344MB download, but after Download it is only 869MB.
Why the difference?
tvuser:~> ls -lAh
total 869M
-rw-r--r-- 1 tvuser users 869M Aug 29 23:36 Page Eight - Page Eight
b0146fz0 default.mp4


The "get_iplayer -i ...." doesn't list a file of that size?

Has anybody an idea what is happening here?

Thanks in advance for any help.

Brian.

ps. here is the output from the download...

tvuser:~> gi --type tv Page\ Eight --hide -g --force
