Tvheadend

First off, great work with Tvheadend. It's a breath of fresh air after using the needlessly-complicated MythTV off and on.

As a little background, I'm a long-time DVR user, both commercial and open source, and a longer-time Linux user. I'm in the North America market and have spent plenty of time with analog, ClearQAM, CableCard, and ATSC. Our household is currently running Windows Media Center (7) with Xbox 360 extenders at each TV, sourced from an OTA antenna. We're regularly testing alternatives, currently Raspberry Pi-based solutions.

My current test setup is Tvheadend 3.4.27~gfbda802 as included with OpenElec 3.2.4 running in a VM with the HDHomerun 3, with RPis for viewing, eventually to move to real hardware. Things seems to be working well overall, the issue tracker was helpful in finding some of the finer points for the NA market. My remaining questions are as follows:

1.) Are channel numbers allowed to be anything except integers? Our lineup here uses 7.1 - 54.1, and trying to use any expected combination (7.1, 7_1, 7-1) all fail to save. The best thing I could come up with is to move all the channel numbers into the 1000 range (1071 - 1541), but that's not very wife-friendly.

2.) Due to issue #1418 (which still remains in this stable version and fixed upstream), I've needed to map all my ATSC channels by hand, which was a bit tedious. Is there a way top copy all of my channel mappings from one adapter to another in the UI? I was able to do it with a small shell script and restart TVH, but it was kludgy.

Thanks!
