HELP! ATI All in Wonder TV Tuner ?

[bleucheese]

I have an ATI All in Wonder 32MB DDR AGP card on an athlon 1.4 with 512MB DDR running WinXP SP1 (phew...thats a lot of abreviations). anyways, my tv tuner had been working fine until recently. i dont know what happened, but for the past few days watching TV uses up to 95% of the CPU and every other program runs extreeemely sloooow. also, when i hit a key to change channels, it takes forever for it to register. anyone know why this could be? i tried uninstalling and reinstalling the latest drivers, but that hasnt helped.

also, during the installation of the drivers, the first thing you need to do is remove the old drivers and reboot. but after i do that, windows begins to automatically install its own drivers for the video card. i havnet found a way to turn this auto detect off, anyone know of a way to turn this very annoying crap off?

thanks!

i would try uninstalling everything thats ati then let windows reboot into safe mode with networking and install the new drivers that way. Then after the installation of the first set, boot normally. I hope that works. I can't exactly remember what I did but hopefully it will work.

My system is comparable and I get no slow downs or lags. I have the AIW Radeon 32mb with XP 1600+ at 1.75GHz and XP SP1. MMC7.7 as well.

I did a fresh install of all of the Catalyst drivers on my wife's AIW and had TV tuner problems as well. She has the same card as you (Radeon AIW 32Meg).

I think that the setup progam for the WDM drivers doesn't do a complete install. I had to go the each WDM driver in the device manager and manually update the drivers.

Go to the ATI website and download the latest WDM capture driver. Run the setup and remember where the inf files are stored (it will ask you where you want to save them).

Next, go into the Device Manager from the Control Panel and check the video section for anything with WDM in the description. You should have 5 or 6 entries. I only had 3 but had 3 or 4 others as undefined devices (yellow question marks). Either way, select each WDM device (or question mark) and choose the update drivers button. Point the update to the ATI support directory that has the new WDM inf files. It worked like a charm for me after that.

Also, if you haven't done it, select the "Optional ATI software" from the driver section on ATI's website (bottom right of screen containing the Catalyst drivers for your AIW). Download the latest MMC (multi-media center) and install it as well.

Just a hunch, but seeing as nothing else changed in your system, did you accidentally switch the TV On Demand from a Live feed to a Time-shifted feed? All that extra CPU usage sounds like it is writing to the hard drive and displaying you a Time-shifted feed.

I used to have the same card as you (now I have the AIW 9700) and I remember doing this very same thing once only to discover I was in "TIVO Mode".

Watching TV shouldn't use any CPU at all ... unless you're not running direct hardware overlay mode (where the TV card pumps the stream directly into an offscreen buffer in the graphics card, to let the latter combine the TV stream with the main computer image). Did you enable some complicated filtering that isn't done by either hardware, disable overlay mode, or did something similar?

OMG! thank you so much! i totally didnt even notice that at all, and now the TV works fine. thanks to everyone for their tips.
now i have this "duh!" feeling going on. at least my TV not working for the past week forced me to study for my midterms.

Watching TV shouldn't use any CPU at all

Radeon's use adaptive de-interlacing and temporal filtering for all video inputs before displaying on the overlay (otherwise interlaced artifacts would be horrible on the computer's progressive display), so there is definately a CPU demand while watching TV...and even more so when using TV on-demand.

Glad to help Bleu. Don't knock yourself too hard. Like I said in my post, I did the same thing. Image quality went down, computer slowed down. Had no idea what happened. Of course it was something simple!
