<br>
The idea of re-cycling old AGP PC kit with a capable recent 9 series video card is appealing price wise and also from a lowered<br>
planetary re-cycling cost. As with VDPAU the CPU requirement is generally vastly reduced. Power consumption and box volume may be a<br>
negative though, compared to new Ion based offerings on the horizon, all be it with unknown delivery dates and then also known<br>
software stabilisation for how long or at all?!! If this is for you, read on and have it (a little?) easier!<br>
<br>
Trying this card in a Gigabyte 866Mhz Intel III GA-6VM7A+ the video card failed to boot despite various BIOS changes including<br>
assigning Video boot to VGA. Known working system otherwise. This has not been exhaustively worked up with BIOS default setting,<br>
checking power wattage (which might not have been up to the said 300W or so...required) however it did not look promising. Might<br>
have another go another day....<br>

Maybe power supply issues contributing with readings like:<br>

with -12V wide ranging from -6 to -16! Take out the tuner card that was there! maybe needs new PSU? Current PSU is relatively new<br>
430W which should be ok? Keep an eye on.<br>

MythTV<br>

<br>
But need to configure the profiles to use vdpau.... Instructions not really clear to me whether one adds the two specified settings<br>
(Ref: <a href="http://www.mythtv.org/wiki/VDPAU#Display_Profiles" target="_blank">http://www.mythtv.org/wiki/VDPAU#Display_Profiles</a>) to an existing profiles of Normal, High Quality, Slim, CPU+, CPU++ or CPU--<br>
(Ref: <a href="http://www.mythtv.org/wiki/Playback_profiles" target="_blank">http://www.mythtv.org/wiki/Playback_profiles</a> ) What I did was add a whole new profile called vdpau, and added the two sub<br>
profiles. Uncheck fade out (which I hate - why would I ever want to wait for fade out to complete?) and then add in the<br>
de-interlacers (Ref <a href="http://www.mythtv.org/wiki/Deinterlacing" target="_blank">http://www.mythtv.org/wiki/Deinterlacing</a> ) which I gather much experimentation with will be required. Also made<br>
vdpau come in with definitions >H0 and W0, else standard which is the ffmpeg one otherwise, as I am using DVB-S its probably just<br>
using ffmpeg, but how would I know? Image crashes after a few seconds.... OK change thresholds to H1000 and W700 which should turn<br>
off vdpau in SD, and what do you know crashes stop.... Mmmm. Reset to H400 W400 and crashes return. Suggests vdpau crashing on<br>
DVB-S signals but ffmpeg ok. Back to H1000 and W 700. Maybe this should be >C4 SD of 720x400 so only 720p and 1080i gets vdpau?<br>
(When I need to how does one make this distinguish non H264 SD channels from H264 SD channels e.g. C4, TV3+1?)<br>
CPU runs ~55% on these now.<br>
<br>
VLC<br>
> VLC: C4 and TV3+1(=SD Definition) on VLC plays ~ 60-100% CPU, as fed from a DVB-T HDHomerun. More CPU or VDPAU is needed to meet<br>
> the Queens (high) standards.<br>
> VLC: TV1 DVB-T plays CPU >= 90% quite unsatisfactorily. NVIDIA Temp ~75 degrees playing these. (Slowdown threshold 105 degrees)<br>
> Probably will only be fixed when VLC gets VDPAU support or when alternative DVB-T source is integrated into BE and plays thru<br>

Still TO DO:<br>
>> When changing the OSD configuration I note the keyboard does not work changing channels etc. Killing the FE process and<br>
>> restarting the FE consistently sometimes persuades the keyboard to work again. Happened repeatedly, likely a bug. Actually<br>
>> seems to happen more than just following OSD changes. Hmmm. Makes it hard to do the repeated channel change test!<br>
<br>
>> Figure out why remote not working....<br>
<br>
>> Fix the hiss playing out one channel. (Odd) The kit (same except 2M RAM instead of 3 and substitute 5200 for 9400GT) previously<br>
>> worked fine with mythbuntu 8.10 / SD.<br>
I note some repeated comments about buffer overruns in the logs that may be associated, not sure.<br>

But "Extra Audio Buffering" is selected in "General Playback (1/9)" settings.<br>
<br>
Any comments or ideas welcomed!<br>
<br>
<br>
Hope this helps others scratch the surface of mythbuntu 9.04!<br>
