I’ll test this as well when I get a chance. I don’t use this feature as, in the past, it has resulted in some recording instability (likely due to resource utilization) on my system. Also, it doesn’t result in a very great file size savings. It does transcode to H.264, which can improve compatibility, but it leaves it in a TS container.
I’m doing this right now. Two shows are recording from the same tuner, on the same virtual channel. I configured one show to record, and then the following show to record with a 20 minute padding on the front.
Here they are, both recording:
And here’s my tuner usage:
They’re both recording from 4.2. Tuner 0 is in use by NextPVR.
[Edit]
@taraba BTW, this is with the option to convert while recording enabled.
