I'm getting a "Failed while negotiating" message on mine.  Last successful connection was Thursday morning. 

Thread here about it on Oz TiVo forum but no conclusion

Same here. I've messaged the people who look after the EPG server, so hopefully will get a response this weekend, all going well. 

Have been following the OzTivo thread - after watching the Crusaders getting beaten by the Hurricanes.

Just tried updating and everything appears to be working again.

Big sigh of relief.

Will confirm tomorrow morning after the download has sorted etc

Thanks to Spong for chasing up. 

Yes, working again.  Sorting not yet completed but downloads normal.  OzTivo thread says the same.

Thanks again and a very happy Sunday.

Thanks for the heads up guys. It turns out one of the Australian Admins had made some changes to the EPG server (which supplies both the Aussie and NZ EPGs) and had broken it. It's now been fixed, so should be good now.
