Reasons for PVR150 IRBlaster to fail to change channel?

[tieke]

Just seeing if anyone has had this before/knows why a PVR150 IR-Blaster simply wouldn't work. I have two cards - a Twinhan DVB-S one, and a PVR150, which uses it's attached IR-Blaster to change channels on the cable box to which it is attached. A program was recorded with the PVR150 at 5.54, and everything worked appropriately:

Code:

However a couple of hours later, a program was recorded with the DVB source correctly, but a subsequent PVR150 program simply didn't change the channel, so recorded on the wrong one:

Code:

I have restarted the recording service, and the channel changer appears to be working correctly at the moment, but then again, it was working OK earlier today as well.

Any ideas what the "UIR_GotoChannel() failed: 1" message means? (apart from the obvious that is) or is there some way to force GB-PVR to retry changing the channel if it doesn't work the first time?

cheers,

Try using the .exe channel changer instead, and point it to c:\programfiles\devnz\gbpvr\HaupBlast.exe

I had a similar problem. It would record off of the internal tuner with no problems , but every once in a while when it needed to change the channel on my STB , it wouldn't work. No pattern to when it would work or not. Doing as Sub suggested and using the .exe channel changer has so far fixed the problem.
