Firstly, the same ep (Adam) has two entries:
<http://www.bbc.co.uk/iplayer/page/item/b008z1rb.shtml?filter=category%3A100
003&start=2&scope=iplayercategories&version_pid=b0090rc1>
http://www.bbc.co.uk/iplayer/page/item/b008z1rb.shtml?filter=category%3A1000
03&start=2&scope=iplayercategories&version_pid=b0090rc1
http://www.bbc.co.uk/iplayer/page/item/b008z1rb.shtml?filter=category%3A1000
03
<http://www.bbc.co.uk/iplayer/page/item/b008z1rb.shtml?filter=category%3A100
003&scope=iplayercategories&start=2&version_pid=b008z1r5>
&scope=iplayercategories&start=2&version_pid=b008z1r5
They're both shown as 500Mb but one is 292Mb and one is 270Mb, they're both
from BBC Two and they're both 50 minutes... What gives? Also, on their
download pages where you can click to initiate the download, it looks a bit
broken:
[pink arrow] Download
File size: 500MB
[pink arrow] WarningsNone version
File size: 500MB
Both links seem to achieve the same thing, although clicking on both on one
page first started the download, then showed me an error dialog which said
"sorry - our servers seem to be a bit busy at the moment" error message
(which I found quite amusing :)
Not seen that little kludge on any other iplayer page though, what gives?
(both entries for that episode of Torchwood do have a parental guidance
notice).
