OK, I've done some testing with the 1.0.0.6-2 build and the QBOX S2 5922
1. Using VDR
I can successfully scans and finds all the FTA and encrypted S1 and S2 channels (Sky NZ) using the start up menu
When using the VDRVNSI client within XBMC the playback on FTA channels are extremely choppy and the image appears interlaced around any movement. I've configured OSCAM to connect to my remote server but it does not seem to work. Channel selection becomes unresponsive after a while
When using the DVRXVDR client within XBMC the playback of FTA channels is also extremely choppy and the images appears interlaced around any movement. OSCAM is configured but again it will not decrypt any channels. Channel selection is working smoothly
2. Using TVheadend
I can successfully scans and finds all the FTA and encrypted S1 and S2 channels (Sky NZ)
When using the TVheadend client within XBMC the playback on FTA channels are extremely choppy and the image appears interlaced around any movement. the good news is I can successfully connect to my remote OSCAM server and decypt the channels. The bad news is after a few minutes TVheadend loses all its configuration and it needs to be re entered.
So to summarize, all methods are producing a choppy, interlaced image on both SD and HD channels. I'm keen to to understand if this is a common problem for everyone or related to the QBOX S2 5922 I'm using
Connecting to OSCAM is not working for VDR
Connecting to OSCAM is working for Tvheadend
TVheadend loses its configuration after a few minutes
