Can't handle http://downloads.bbc.co.uk/rmhttp/downloadtrial/fivelive/markkermodesfilmreviews/rss.xml currently.
When I click on the link it doesn't open in a browser window.
Same with http://www.aintitcool.com/index_scifi.xml
They work in other rss programs.
(if they work for you good - but they don't work here, so there is a parsing bug somewhere)
If you are referring to v 2.9 I've found there are a lot of bugs in it. Revert to previous version or put up with it and wait for next version.
The version immediately prior to 2.9, think it was 220.127.116.11.6. I found it more bug free than 2.9 although 2.9 has improved features whenever the bugs get stomped on.
I'm always refering to the latest version. What previous version?
