Resume from Standby -> TV gives Access Denied error

[MartinPVR]

I have an issue with resuming from standby that I am hoping someone has had similar difficulties as it is a bit odd. If I manually Standby the the PC and then wake it, go to Live TV, everything is fine however if I Standby, manually record a show then wake the machine then when I go to view Live TV I get an error 'Access Denied'. It seems I can schedule any number of Timed recordings that wake and sleep the machine and they all record fine.
I set up the standby mode according to article - http://support.microsoft.com/default.asp...%5D;841858
as this fixed some waking issues with the RedRat controller when I was running with Showshifter.
The machine is running a fresh install of XP with a Hauppage 250 card and an ATI Radeon 9250
Could GBPVR scheduled recoder be not releasing the tuner?

Please let me know if you have any ideas

Thanks

Martin
