Any tricks to get RSS module working?

[MikeNZ]

"Cannot read data from the selected RSS channel. RSS format is invalid.

ScriptingNews, PC World and MSNEntertainment works fine.

CNN gives me a blank page, but does work on preview page

MSNBS top news gives the following error:
"Cannot read data from the selected RSS channel. RSS format is invalid.
The selected RSS channel is unavailable now."


Thanks in advance.
