Lost functionality in ATI MMC since catalyst upgrade

Ever since Catalyst 3.6 (I'm now on 3.8) I've lost my TV on Demand
functions, and the TV tuner no longer appears as a capture source. I've
upgraded MMC from 8.5 to 8.6, and finally to 8.7 to see if a reinstall would
help, but it's no different. Each time, I've completely removed all ATI
software and drivers before installing the new ones.

I can select the TV tuner in Windows Movie Maker but I can't tune it.

Investigating further, I ran the MMC PC check, and it says my processor is
non-MMX. This can't be right - it's a 1.8MHz Pentium 4, and used to work
just fine. Just to be sure, I've run Passmark's Performance Test V4.0, and
all the MMX tests pass with flying colours.

I've made no changes in the BIOS, and as far as I can tell (I don't use it
all that much) it's only started happening since Catalyst 3.6. The only
thing I can find on the ATI support site is to check my BIOS (which I have, though I can't find anything obvious that would affect this) and make sure I have the latest BIOS update (which I do).

The card is a Sapphire AIW9700 Pro, and the motherboard is a Gigabyte
GA81RXP.

Any ideas?

 
All I can say is that I got that same sort of message, that my Athlon xp1800+ wasn't mmx, and more removing and installing seemed to help. Two suggestions, a program called I think Driver Cleaner that removes all the bits of ATi that uninstall leaves behind, and don't forget to set the display device to pci something (sorry I forget, but mentioned in lots of the readmes).
 
The MMX not detected message is a bug in the MMC 8.7 utility. MMX is used according to posts at
rage3d


As another data point, I upgraded an AIW VE from Cat 3.7 to 3.8 and MMC 8.6 to 8.7 and all continues to function.
 
I Don't know why, but I always seem to forget that Rage3d.com exists!

Thanks for reminding me. I found a thread here that deals with the TV tuner issue, and points here for a fix.

I've just installed the fix, and it works perfectly. Not even any need for a reboot. Only problem is the volume on the TV tuner is almost inaudible, but that doesn't matter to me. I've got my TV-on-Demand back, that's the important thing. Now I can pause digital Cable again! 😀

So the MMX bug was a red herring. Nothing to do with the problem.
