Channel changer not working during recording

[pcabot]

Hi,

I have an Hauppauge 1600 and Vista ultimate (latest driver from the website), with a sa250HD cable box. I am using the IRblaster that comes with the card.

I have read many posts about this problem, and I even changed my service to "allow interact with desktop", but the channel changer won`t change during recording (quick or scheduled).

The channel changer works fine from the command prompt and from the IRblaster configuration. The channel changer also works when watching live tv from the TVGuide (which means that haupblast.exe gets called properly).

It looks like a permission problem. I tried running the recording service with the current user permissions, I have the same problem. I even tried the "runas" trick that someone mentioned in another post, and same problem.

I was wondering if the haupblast.exe is the only way to change channel inside GBPVR with an Hauppauge card ? I saw that HIP can be used, but I cannot find the information about the configuration for the haupauge blaster.

Anyone has any clues ?
Thanks a lot in advance.
I think that GBPVR is awesome and so easy to use ! I just hope to be able to change channel during scheduled recording !

Update: I even tried disabling totally UAC (after reboot), and same result: the recording won't change channel.

I even tried changing the channel changer exe to notepad.exe.
When I record, Windows tells me that another process is requesting attention in another desktop (which is notepad). Therefore, the haupblast.exe is called properly, but it seems that the haupblast.exe won`t work when called from the service....

This is the only issue I'm aware of that could have been the cause, and would have been what I would have suggested.

I can see its definitely running it, and no sign of any error codes being returned.

Thanks for the fast answer.

Do you know if there is other way to fire the hauppauge IRblaster ? Because it seems that haupblast.exe seems to be the culprit, and not gbpvr as you highlighted (yay!)

I saw that gbpvr supports HIP, but I don't know where to find the exact details on how to configure it to blast the hauppauge blaster.
Any pointer on alternative to haupblast.exe would be great,
Thanks again,
Phil

I wrote HaupBlast.exe as well, but its only six lines of code, and simply calls a function inside Hauppauge DLL, so I dont think HaupBlast.exe is directly responsible. Hundreds of others are using this from the recording service without problem aswell, so this makes me think its got to be something funny with permissions or similar on your machine - hard to guess what exactly though.
