[mythtv-users] Cannot change channel and "low FPS" problems

[Rickard Borgmäster]

Hello,

Could someone please explan what is what of:
* Channel ID
* Channel number
* Channel callsign

This is what it looks like in my database:

mysql> use mythconverg;
mysql> select chanid, channum, freqid, sourceid, callsign, name from
channel;
+--------+---------+--------+----------+----------+---------------+
| chanid | channum | freqid | sourceid | callsign | name          |
+--------+---------+--------+----------+----------+---------------+
|   1000 | SE11    |        |        1 | 1000     | Kanal 5       |
|   1001 | E5      |        |        1 | 1001     | Svt 1         |
|   1002 | E7      |        |        1 | 1002     | Svt 2         |
|   1003 | E6      |        |        1 | 1003     | TV4           |
|   1004 | 57      |        |        1 | 1004     | TV4 Plus      |
|   1005 | E11     |        |        1 | 1005     | TV3           |
|   1006 | E8      |        |        1 | 1006     | ZTV           |
|   1007 | E10     |        |        1 | 1007     | Discovery Mix |
|   1008 | SE17    |        |        1 | 1008     | Eurosport     |
|   1009 | SE16    |        |        1 | 1009     | MTV Nordic    |

1001...1009 has been autogenerated from somewhere I think, maybe
tv_grab_se_swedb or such. I don't know it is correct and I am afraid to
"fuck something up" if I change those numbers. I'd like to map channels as
one would do with a plain ol' TV (National Channel 1 -> Button 1 etc).
What should I change?

I have probems chaning channels in myth. Picture is displayed OK and I can
use ivtv:s "ptune.pl -c SE16" to watch MTV. If I try to change channel in
myth, picture freezes for a second or two and then the same channel is
still displayed. Mythfilldatabase is OK i think. EPG info an such look
good. Maybe it has something to do with the above channel setup? Or maybe
MythTV relies on some tuner script that it can't find? Or maybe it is
because the "freqid" field in the database is empty? (What is this field
for anyway?) My channel plan is PAL europe-west.

There is another problem aswell. Picure is "slow motion". Feels like it
would be ~10 FPS or such. Strange. Playing video like "mplayer
/dev/video0" is all fine.

Myth system specs:
Gentoo 2.6.11-r6 kernel
ivtv 0.3.4b
mythtv from CVS grabbed 2005-05-04
CPU: Intel PIII 800Mhz
TV-Card: WinTV PVR-150 (non-MCE)
Graphics: NVidia FX5200 with nvidia binary driver 1.0.6629
