tv.com syntax problems

HI guys,

Recently I've been having some problems with tv.com  I can grab a few channels ok but then I start getting the following message:

[  Info  ] (  53/221 ) TV.COM -- chan. (xmltv_id=A&E Network HDTV (A&EHD)) -- mode Incremental
[Warning ] 
[Warning ]   !! -- WARNING : tv.com doesn't allow epg grabbing !!

[Error   ] Unable to update channel A&E Network HDTV (A&EHD)
[Critical] Generic syntax exception:
[Critical]    message: 
[Error   ] no index page data received from A&E Network HDTV (A&EHD)
[Error   ] unable to update channel, try again later
[  Info  ] No guide data to restore

If I move this channel (for example) to the top of the list in my config file it grabs ok.  

I've got the latest ini file and I'm running 1.56.27

Any ideas what is happening?
