ATI 690G/x1250 problems (48 Viewers)

And if I want to chance a channel this window pops up:
From the screen shot it apprears you ahve a recording running. How many tuners do you have. That error means that there are no free tuners available.?
I´ve did some comparison tests of 1080i material (true interlaced, 50fps, capture from DVB-S2):
690G/x1250 with X2 BE-2400 CPU (2x2,3 GHz, my HTPC) AGAINST my PC at work (Xeon DualCore 2x2,66 GHz, 4 GB PC800 RAM, nVidia Geforce 8800GTS)
Latest nvidia drivers, latest Cyberlink PDVD Ultra patch, CoreAVC 1.6.5 witc MediaPlayerClassic
- hahaha the picture quality is NOT BETTER (fast movements are not fluider, scrolling lines are not deinterlaced nicer) with the 8800GTS, hardware accelerated
- the nVidia hardware deinterlacer is not better than the sofware deinterlacing of the PowerDVD or CoreAVC (best they can do is bob or blend; visual impression of quick scrolling thin lines concerning fluidity, sharpness, ghosting)
- only advantage is lower CPU usage (but more GPU usage) = overall my HTPC has surely lower power comsumption despite 70-100% CPU usage
I have to review my opinion: the x1250 is not so bad at all, you need only a beefy CPU (2x2,3 upwards), good configured codecs, fast and big dual channel RAM, and Vista. The limitation in picture quality is the source file (shitty interlaced). With 1080p you can have superb picture.

it's frames per second that count, the 8800GTS will handle a far higher fps, but for HD playback the fps are fixed by the video format so does not matter.
Now if you want to play the Latest games at full specs, then you would see the 8800gts wipe the floor with a x1250, but that not what it is designed for.

However, your review is only true for Vista - for those of us on Windows XP, the ATI CCC drivers do not enable 720p, 1080i or 1080p with hardware acceleration in the x1250.
It seems that ATI have only bothered with Vista drivers for the 690G/x1250, and are not interested in fixing any of the bugs in the Windows XP drivers ...

Ok...probably been answered on this thread many times but its too huge to search...
Is there a fix for the hdmi to send a signal when changing tv input? Its such a pain to reboot the box if i want to watch my mediaportal!
If I understand what you are asking, the problem isn't with Mediaportal, but the equipment you have attached to it. I used to have my Media PC directly attached to my TV and all was fine. I could swap inputs at any time and it would display whatever input I wished.
I have since purchased an AV Receiver with HDMI inputs and now have my Media PC connected through this. If my PC now reboots (say for a Windows Update) and the PC isn't the current input at the time, when the PC starts, the video doesn't initialise correctly and won't display anything on the TV when I change inputs. This is because the HDMI connection has no signal at boot up, so the hardware doesn't initialise the display. I don't think there is an easy fix for this, so I just have to live with it.
Yes, true. I admitted it also, you need Vista. BTW I am not so keen on the Hardware Acceleretion of the x1250. It can only accelerate mpg2, but do I need it? My CPU can do the job just as good. The only thing is HW deinterlacing, but I guess that the x1250 cannot do sofisticated deinetrlacing like adaptive etc, or a better deinterlacing as my CPU with software can (I played a lot around with several CCC settings and codecs, a simple software bob works the best). And it cannot accelerate h.264 at all.
mpg2 acceleration I do not need, h.264 acceleration it cannot handle.
Vista vs. XP:
it looks like the new 780G chipset has full feature support only for Vista (under XP no HW-Acceleration for video decoding, no hybrid XFire...). Check it out here:

Quickly browsed and searched the release note, and found nothing. (What a big surprise).
