Why 25? Because you can skip forward at the play-dead whistle and catch the next snap without watching the huddle. This way the entire game takes about an hour to watch. -- Trey ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

I found it quick and easy, and wouldn't have a problem recommending it to most folks. I did run into a problem installing kernel modules compiled outside of the header-source tree of the as-installed kernel. In particular make -C /lib/modules/`uname -r`/build M=$PWD modules_install fails because the Makefile doesn't have EXTRAVERSION set properly and so places the built modules in the wrong directory. They have a .extraversion file, but kbuild doesn't use it.

[mythtv-users] Missing DVB channel scan for ASTC Air2PC cards
Howdy all, I've spent some time recently trying to bring up a pair of Air2PC cards without much luck. Turning on some verbose debugging yields this: Starting up as the master server. 2005-04-18 22:31:22.751 New DB connection, total: 2 2005-04-18 22:31:22.755 SIParser: About to do a reset 2005-04-18 22:31:22.755 SIParser: Closing all PIDs 2005-04-18 22:31:22.756 SIParser: Using DelAllPids from SIParser which does nothing 2005-04-18 22:31:22.756 SIParser: Resetting all Table Handlers 2005-04-18 22:31:22.756 SIParser: SIParser Reset due to channel change 2005-04-18 22:31:22.756 DVB#0 DVB SI Table Parser Started 2005-04-18 22:31:22.757 SIParser: Starting DVB Section Reader thread 2005-04-18 22:31:22.757 DVB#0 Using DVB card 0, with frontend Nextwave nxt2002 VSB/QAM frontend. 2005-04-18 22:31:22.757 DVB#0 Trying to tune to channel 11_1. 2005-04-18 22:31:22.758 SIParser: Starting SIScanner 2005-04-18 22:31:22.759 New DB connection, total: 3 2005-04-18 22:31:22.760 DVB#0 ERROR - Could not find dvb tuning parameters for transport 0 2005-04-18 22:31:22.760 DVB#0 ERROR - Failed to get channel options for channel 11_1. 2005-04-18 22:31:22.765 SIParser: About to do a reset Notice the "Could not find dvb tuning paramters for transport 0". It seems to indicate (through looking at the code) that I have an empty dtv_multiplex table. In fact, poking around with mysql tells me the table has zero rows. Prior to 0.18, it seems that the recommended action involved scanning for the channels in mythtv-setup. Unfortunately, CVS (as of midnight Central time, U.S.) doesn't seem to have this feature. Where did I go wrong? I had a mostly-working HD-2000 v4l setup before I switched over to the Air2PC cards. I've dropped the card and channel configurations twice, but dtv_multiplex never seems to get filled in.

My local CBS station has regluar programming on 11-1 and other stuff on 11-2 and 11-3. Eventually they say it will grab the entire encoded stream and pull out the sub-programs. -- Trey ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

StormLogic did get them in earlier and sent me two emails trying to confirm, but I didn't read my email in time. They went over and above what they promised, even though I managed to flub it. I'd order from them again if I have the need. Now I just need time to bring up the cards in my backend. -- Trey ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

[mythtv-users] How do I remove a video source?
Howdy all, I've made a mistake and have a duplicate video source defined. I'd like to remove it, but I didn't find any way to do so from within setup or mythfrontend. Google'n for "MythTV remove video source" or "delete video source" didn't turn up anything. The online documentation only tells you how to add sources. Suggestions? -- Trey ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
