Kworld 120 tuner - what should I expect?

Hi...

I just installed a Kworld 120 (the successor to the Kworld 115 & 110 ATSC tuners) into a Debian mythtv box. I am using a recent (several days old) version of v4l (pulled using Hg).

Things appear to be running, however I still can not tune in any ATSC stations (another mythtv box split off the same antenna is receiving over a dozen ATSC stations). I have not even tried to get the Kworld 120 NTSC tuner working.

As Kworld 120 support is new, I was wondering what to expect. There have been threads pointing out this new and very different version of Kworld tuners has to be rebooted in order to switch between tuning ATSC and NTSC signals. I wonder if that is still true. And, if anything, what else I should expect.

Also, what are the best tools to configure & test this type of hardware and how do you use them? Running through mythtv-setup every iteration does take time.

...thanks

I know working off of "v4l dvb staging" is risky business, but I'm trying to get the new Kworld 120 tuner (replacement for the old Kworld 115 and older yet Kworld 110 tuner) to work.

I'm running a scan (which I assume is the old scandvb?? which I can't find anymore) on both of my mythtv Debian boxes. My master back end has a Kworld 110 and my newer slave front end has a Kworld 120 card. I'm only running "v4l dvb staging" on the newer slave front end.

The scan output on the master back end shows 33 services. While the scan output on the new slave front end shows 0 services. I should next check the antenna hook up on the slave front end - but, if anything, it should be a good +3dB better then the slave back end (having one less splitter).

I would appreciate hearing from anyone who has had success with the Kworld 120 in a mythtv box.

...thanks.
