I just bought an ati hdtv wonder card and I'm having trouble with the audio and video studdering. at first I thought it was my pc(2.0ghz AMD64 768mb ram) after doing some reading and testing I now think it is the weak signal i am getting. I live about 30 miles away from the city all the stations are comming from. There is one station that comes in pretty good and signal strength is 4 out of 5 bars. The audio/video studders about every 10-15 seconds on that channel. on all the other channels the studdering is non stop. I tried a indoor amplified antenna and it seemed to make no difference. I tried both antennas inside and out and pointing them in different directions. would an outdoor antenna work any better? I cant go with anything huge, I'm in an apartment, or am I just screwed? Thanks!

If you are using the ATI software you can click on the little antenna button and will show a graph of the signal. I notice for me to get a good image I need something around a 70% or better signal. I'm using a AMD 2700 and when I get a 1080i signal it's at about 20-25% CPU utilization (I think).

ok, I checked and the signal strength on most of the channels is around 66%. cpu utilization is only 25-40%. I dont know what I did or what happened, but I was watching hdtv on the thing, the computer rebooted and when I went to watch hdtv again it played perfectly on almost all channels except the ones with really weak signal. I watched tv for a couple hours with only a couple of hiccups. Then I closed the tv program, plugged in the usb remote receiver, went to watch tv and its back to stuttering badly again. I removed the remote receiver, even uninstalled the software, rebooted a ton of times and i cant get it to play smoothly. I just dont get how it played fine after it crashed, but now it wont. I tried removing all pci cards, this is really frustrating.

You can get tv from an antenna? WOW! Who would've thunk?

got it working good now. had to completely reinstall windows and move the antenna outside to get fox and the wb. all other channels come in ok.

I had the same prob with the studder... on a AIW 5700(?), especially when using s-vid for an external DVD... and now the prob literally solved itself... my friend thinks the capacitors needed to be 'warmed up'.... whatever it was... works fine now...

Have you tried this ap. yet? It's free. Most people say it's way better than software from ATI.
