I'm not sure I understand what you mean when you say "set it's chanid to a number within the numeric range of known-good channels". I assume you are controlling an OTA ATSC Set Top Box. So, I would not expect a channel like 17 but rather a channel like 17_1. It looks like the channum element of the structure is used in mythtv_mysql.c, tvguide.c and mythtv.c. You would have to go in and not only add things like channum_major and channum_minor but also change the code to handle the new data. It could be a lot of work depending on how you go about it. I really doubt you can get away w/o changing the code. I am assuming the above didn't work because the actual channel number in the data base is 17_1? But I'm only guessing. (As a hack, you might try a quick fix where you append "_1" to all mysql queries. That might get you access to information about the first channel in a broadcaster's set of channels.) I remember posts here about mvpmc having problems accessing multiple tuners. But I don't use my mvpmc boxes for live TV so I don't know if that was resolved or not. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Mvpmc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/mvpmc-users mvpmc wiki: http://mvpmc.wikispaces.com/
