Hi, this is the scenario: I just got an AIW 9700 Pro and it's great. But:
I have my antenna cable from the wall going into a splitter, and then I have a cable going to my TV and a cable going to my AIW. The TV gets a perfect signal but my AIW gets crackly noise and static in the graphics...any ideas on fixing the interfence in the tv tuning of my AIW card? Thanks.

First try swaping antena leads.If that clears it up you have a bad antena cable.Second,try antena lead direct.If that dosnt clear it up you dont have enough gain for the AIW.My AIW7500 requires an amplified antena signal.I also have my signal split from a rooftop non amplified antena and get a slightly better picture thru my sony TV tuner.I think both cards use the same TV tuner.Third ,purchace a 3db-6db line amp and install before the splitter.

Am I looking at the right prodcuts? I'm finding catv amps at radioshack.com for like $30...?
Thanks for your help.

What kind of splitter are you using? The flimsy looking generic ones like you'd find at Radioshack aren't so hot, they have 2ghz splitters for like $10 at BB or CC. Huge difference in picture quality vs. a standard splitter.

PS. Where'd you get the AIW9700pro? Through ATI? I was considering getting one, but I got an Asus TV Tuner instead.

It says - 900 Mhz splitter. Looks pretty generic. Got it @ Walmart.

I got my AIW9700Pro through the preorder promotion at ATI, so I got a TV Wonder VE free.

Well, I hooked up the feed straight from the wall and I still got static, so I think I need an amp like teo said, not a splitter...

Dunno, could be the TV tuner itself. Not sure how though, as reviews said the 9700pro tv tuner was just about the best around. I went through a similar experience a week ago with the Pinnacle TV Tuner. IQ was terrible with wavy lines and fuzz. Thought it was the splitter to my cable modem, but I tried a straight line from another room and it was still fuzzy. Swapped it out for an Asus TV 880 and IQ is simply awesome. Are you using both the TV wonder and the AIW's Tv tuner? I'd stick with just the AIW, as the VE is on par with the PCTV (crappy).

Nope, right now I only have the AIW in my system. I figure with the 4 computers and all their cables I have messed around under my desk, there could be interference easily. Maybe I need better cables as well? I kinda went the cheap way and got cables and splitter at Walmart.

You haven't said weather you have a rooftop antenna,set top rabbit ears or cable.the fact that when you hooked the antenna directly to the 9700 the picture quality didn't clear up or improve leads me to belive the problem is with the main lead in or the AIW tunner.I am also assuming you are using rg-59 cable(co-axial),the picture is degraded on all channels(not on 2 thru 13 only,14 thru69 only).You might also try hooking the main lead back up to the AIW and RE-SCANNING for the channel presets to see if that improves your signal.I'll have a AIW 9700 on tues and let you know how the tunner stacks up to the AIW7500 P.S.I spent about 15 years in the TV and Stereo busness.Antenna signal was always one of the hardest problems to solve.Even cable signal degrades when split and low quality parts are used..TEO

I have a college cable connection right into my dorm room. I think it's downloaded from a satellite or something because it looks kinda of fuzzy sometimes on my TV set. I tried connecting the co-ax cable straight to my AIW and the interference was a little less, but I still could hear some crackly sound (I did notice that some channels were better than others by far, though...the video is always pretty decent but the crackly sound is what gets to me. In particular, ESPNews is horrible. TBS and other stations are pretty good.) Well, that's about the whole story, I guess. I was thinking about picking up an amplifier soon...because I had some crackly noise on some channels while my AIW was hooked directly into the wall, it's not the splitter that's the problem.

Your video problems may not totaly be able to be cured.A line amp MAY help but i would doubt it.if your signal out of the wall is giving you picture problems a line amp is only going to amplify the picture problems.the signal has to be clean before you amplify it.There could be a cable connector problem at the junction or distrubition box in the dorm.If you can try your system in another room(preferably some distance and a different floor)and your problem clears up you know where the problem is.As for the audio problems,this should help for now. open your TV app.2right click on tv display and select setup.3.Select TV tunner tab.4.Highlite channel that corrosponds to ESPN in left pane and click DETAILS .5.Check AUDIO in CHANNEL SPECIFIC SETTINGS box and click details to bring up sound settings.6.try changeing from GLOBAL to either "stereo" or "mono".This should fix your sound problem.Most cable systems dont have enough gain for proper channel seperation in stereo,thus the stereo tunner slips back and forth between stereo and mono creating noise!I shure hope this helps you out,i'm not used to typeing so much,I've been comming to the forums almost every day since the beginning and read,read,read but don't post much...TEO

Amp no good..I think I'm just stuck with my problems...my friend uses a WinTV and has no problems... =[ Oh well I guess I won't worry about getting good TV reception with my AIW then and I'll stick with it just for gaming.

Knightlife:

I have been thinking about the AIW 9700 Pro. I just want to know what is the maximum capture rate. I have looked at the reviews and no site seems to give this spec, including ATI's.

Thanks.

MPEG-2 720X480 8Mb/s is the max capture setting.
Click to expand...
Thats the max setting "preset", but you can capture MPEG-2 up to 15 MB/s using custom capture settings, and of course you can capture uncompressed full resolution AVI.
All the AIW cards will support the maximum analog capture resolution/rate.
