Hi Mike,

No, where I say:

>> sure this was the point when the 0B file was created again. 

...this was at the same time as watching another channel on a different mux, so this was using another physical input on my HDHR.

I have one HDHomeRun-3 (dual tuner) with the 'max recordings' set to 2 per tuner, so 4 logical tuners.

Yes, I did set the timeouts outlined above on both physical tuners in mythtv-setup. After the testing I did which I've outlined above, I then reverted my timeout settings back to the defaults so that I would get a fair test when I tested anything new on the system. 

I'd been monitoring ticket #10443 so I was aware that a fix for this issue was committed by Daniel Kristjansson on 22/03/2012. As soon as a build that included this fix was available through Mythbuntu repos, I upgraded. Since then, live TV has been clearing up these 0B dummy recordings with no problems. I would therefore consider this as fixed.

Would you like me to do any further testing on it anyway to make sure?

Thanks for your time.

Joe
