I have a HVR-1600 which is a single DVB device with a single V4L2 device, a HVR-2250 which is a dual tuner DVB device and dual tuner ivtv device and an original HD HomeRun. I think that covers several of your desired scenarios. As I was testing I pulled various tables and saved them here: http://pastebin.com/my4TE4ns, the names are the same as mythconverg tables with underscore suffixes denoting when they were taken.

The update went OK and the backend was able to record afterwards (_preconvert & _postconvert).

Deleted my two 2250 devices and recreated them, I screwed up the first attempt so there might be a gap in numbering. The two 2250 tuners were then re-added with 4 simultaneous recordings rather than the 2 I usually run with (_add2250).

Deleted my ivtv tuner and re-added it along with the two analog tuners for the 2250 (_addivtv).

I then added input connections (_addedinputconnections).

I don't see how to configure each input on a V4L card. My various IVTV devices have tuner, svideo and composite inputs but I don't know how to configure more than one at a time. I think I've done this in the past so something may have changed and left me disoriented.

Also not sure what this is.

I ran out of time to do much testing with recording mostly because I'd have to rescan the on dvb device I deleted and recreated but the devices I didn't delete/recreate continued to work as before. I did schedule three subchannels on the 2250 which was recreated with 4 (virtual?) tuners and the scheduler did know to put then all on that one device. When it came to start recording it failed due the device's channels to not being scanned but the scheduling part seems fine.

If you want something else or more detail I can test again Monday and Tuesday and then I won't be able to do anything for a week.
