Asus mobo
2200 Sempron
pchdtv hd-3000 capture card
Radeon 9250
512 ram

My understand is that the hd-3000 has out of the box support in mythtv. If I choose pchdtv then try to bind that card and input to a video source mythtv seg faults. When I choose generic V4L everything was working ok.

Ever since I updated the radeon drivers from the ati site my live tv and recordings and all in black and white, with interference. When everything was working 'ok' the picutre was jerky, audio was out of sync, and colors were off. Updating the radeon drivers was hoped to fix the herky jerky video output.

I did notice an output from the console saying something like 'couldn't find color map' or something similiar, 'mythtv needs this so you probably wont see video'.

During bootup linux detects my card as a Wintv2000. I just assumed the NTSC non-hd portion of the card has the same or similiar chipset as the aforementioned.

Just chaned my tuner type in /etc/mythtv/modules/ivtv to 57 and I have color back with no niterference. Is the analog picture quality on this card poor? The colors are way too saturated and non life-like. Is something not configured properly?

I think I just answered my own question

http://mythtv.beirdo.ca/wiki/index.php/FAQ

""What is the difference between the air2pc and the pchdtv (hd3000) Capture Cards

The HD3000 is an Analog and Digital capture card for digital TV in North America. The Air2PC is a digital TV capture card only. Currently MythTV does not support the analog features of the HD3000. ""

You can change the settings in bulk by doing something like this in mysql:

Code:

use mythconverg;
select * from channel;
update channel set contrast = '16375' where contrast = '32768';
update channel set brightness = '43230' where brightness = '32768';
update channel set colour = '27528' where colour = '32768';
update channel set hue = '56365' where hue = '32768'; 

Or on one line like:

Code:

use mythconverg;
update channel set contrast = '16375', brightness = '43230', colour = '27528', hue = '56365';

Your milage may vary on the color settings. I gave up on the HD-3000 in NTSC as I couldn't get the audio to shut off properly. Sigh.
