ASUS P2-M2A690G + Xine
I've been trying to get my new barebone to show me DVB-T transmissions. I purchased a Hauppauge WinTV Nova-T 500 dual DVB-T tuner card and was hoping I could place the HTPC into my living room. I got all needed Sw installed (list below) and starting to give it a first try. I had been testing the setup on other PC before so everything was quite easy.
Actually the only difference was installing of fglrx.
The list of SW is here:
* BIOS 0601 (18-Jan-2008)
* Fedora Core 7 + all updates available from official repositorys
* latest v4l-dvb-5c2c02dd1bb0 to enable remote control on the DVB-T card
* XineLib 126.96.36.199 + lots of codecs
* VDR 1.4.7 + xineliboutput, skinsoppalusikka, subtitles plugins
The HW I have:
ASUS P2-M2A690G (IGP X1250)
AMD Athlon X2 BE-2350 2.1GHz
Maxtor 320GB HDD
1G Kinston 800MHz DDR2 SDRAM
I got all the preparations made, channels tuned etc. and when I started the system with following command, I only got a not-scaled image which seems to be similar when TV set has lost line sync. It was not as random as in line-sync-missing case, but there was no reasonable picture.
The command used was:
vdr --video=/dvb_recorder --config=/etc/vdr -Pskinsoppalusikka -Psubtitles -P"xineliboutput --local=sxfe --video=xv --audio=alsa --remote=none"
As I said the scaling was not done at all, even it was set to be scaled.
I tried also other video outputs, like xshm, which gave me the best result (it was in no means good). All other options either didn't give any video at all or same as xv or hang the PC completely.
I also tried Mplayer which showed me the video but it seemed to me that HW acceleration was not used at all.
Here is the output of Mplayer with Xv:

I have set videooverlay with aticonfig as said in some other post, but I coudn't find any place to do the TexturedVideo setting.
I also checked Xorg log there is no errors. Xorg.conf is the one generated with 'aticonfig --initial'.
I have been surfing around quite a while now and finally this forum seemed the right place for describing my problem and getting some help.
I forgot to tell that I use 8.02 of fgrlx.
You're having the same problem that many of us are, I believe:
I noticed while still trying 8.02 with X1250 that if the DVB-T data seems to be in 4:3 format it can be viewed but if it is in 16:9 format it cannot be viewed. I could see this by setting the window shape to 16:9 and selecting different channels. If stream is in 4:3, there will be black stripes on left and right, but I can watch the transmission. With 16:9 the whole window is messed up i.e. no stripes anywhere.
It doesn't matter which format the stream is, scaling doesn't work.
My recollection is that VideoOverlay and TexturedVideo get set in the same section. Not sure if you can set those with aticonfig (I think you can) but if you can that would be better than editing xorg.conf since IIRC in the event of a disagreement the aticonfig db wins.
You definitely need textured video or you won't get scaling. VideoOverlay is for older chips, ie below 5xx.

Also, is there any documentation available on the options that are available and their functions?

And some portions of amdpcsdb (cut out some hex values to shorten it... I added Textured2D manually based on some post in some forum, it didn't help. Also TexturedVideo is added manually, didn't help either.
Otherwise this is generated with aticonfig.

Do those files make any sense?
I managed to get 4 channels out of 8 to work correctly by adjusting the screen and view properties. I still cannot understand why those four channels are not showed correctly. Two of those are in same DVB-T multiplex and others are in their own. So all multiplexes except one has one working channel.
The scaling started to work when I retested it today. I don't understand why it didn't work earlier even though I booted the machine.
So conclusion is now such that scaling is now working for all channels. I can get the picture showed correctly or the mixed picture, but both of those are in right size.
The used output is Xv.
I need to figure out what is different in those four channels. Maybe the decoding is not done correctly. It would be very much appreciated if someone could give me any hints where to start from.
