Problem switching between digital and analog

[nippywiffle]

Hi,

I just installed gbpvr 1.0.16 on a fresh winxp install, with all updates available at windowsupdate, and the latest nvidia driver for my geforce 6800gt + latest driver for my hauppauge hvr-1600. I also installed 4 gbpvr patches that seemed to apply to me from the 'survuval guide' thread.

I have my cable connected to both the analog and digital input on the hvr-1600, and successfully picked up all my analog channels, and around 6 or 7 clear QAM channels on the digital side.

Everything seems to work pretty well when I only use analog, or only use digital, but when I flick through the channels, and it goes from an analog to digital channel, or from a digital channel to an analog channel, I lose my video and audio completely. However, after quitting pvrx2, I find that in my timeshift folder, it was still recording everything that i was not seeing on the screen, successfully.

I am using the nvidia purevideo decoder 1.02.223, an no other decoders are installed.

Any ideas?

Thanks for any help,
Dan

If you enable live preview mode, does it work fine?

If you enable live preview mode, does it work fine?

Yes, when I use livepreview mode it has no problem switching between analog and digital. I switched off live preview because with livepreview turned on, the audio is always totally out of sync with the video... I also prefer for it to be recording whichever channel I switch to.

Is there any way around the digital-analog switching problem?

No, I think there is something wrong with this specific scenario. I've seen a few posts about it.

I think its only when you switch between a HD and SD channel. We dont have HD here, so it's not something I've ever tested.

I've added a new setting in the config app for the next release that should fix this.

Cool, I look forward to testing it out. What's the setting going to be called?
Any idea when you're planning to release this?

Thanks.

Its <AlwaysRestartTimeshiftGraphOnChannelChange> in config.xml.

Its probably going to be a while. I just started working on the new release last week.

I’m having a similar problem. Vista Home, 1.0.16 using PVXR2, HVR-1600 for analog and digital live TV and HVR-1800 for recording analog.

When I switch between analog and digital in Live TV (doesn’t matter which way I go) PVXR2 locks up. I have to go to task manager to kill the process to continue. I can go back into PRVXR2 and it will work fine except for the changing between analog and digital, same lockup. LivePreview is enabled. I get the same results with or without the LivePreview box checked but I do suffer from the audio/video out of sync sometime with it enabled.

If I run setup right after a lockup, I will always get a message that “GB-PVR is currently recording” when exiting setup. If I go back into PVXR2 after the lockup without running setup, I can’t find any indication that the system is recording.

Sub, I know you said that you are working on it for the next release but I figured that maybe a little more information on another system that is having the same problem might help. Thanks again for your efforts.

Are you also using timeshift mode? ie, live preview is fine?

[BamBam]

No. Not using timeshift.
