Deinterlace error - failed to locate filter

[ubu]

I get this message in the gbpvr.exe-native.log:

FindFilterByName failed to locate filter: None

I get the same message whatever I have set the deinterlace filter to. Tried running Deinterlace.ax (swag) but it made no difference. I can't seem to find any threads that address this question directly. I've seen it in other people's log extracts but nobody comments on it. I've attached a fuller extract from the log so you can see the "context" of the message.

I'm playing with deinterlace settings to try to get rid of a persistent audio lag. I've tried different audio and video decoders, stopping any background services, etc. but no joy. I see that some people have solved this by changing deinterlace settings. The lag seems to vary its duration (sometimes only just discernable) for no reason I can pin down but is consistently present on all channels and in both live preview and timeshift modes. I'm using the Hauppauge standard (orange label CD) driver. Read the quartz.dll discussion but it didn't seem to apply to audio delay issues. Anything else I should try?

I seem to have asked two questions for the price of one, here. Sorry.

Just ignore those messages. They're normal.

The encoder pass through option is the least likely to have any audio sync issues. If you still get them with this, it may be worth trying different audio/video decoders to see if it helps.
