Windows 7 64Bit Compatible Tuners
Does anyone have a recommendation for a USB TV Tuner that is compatible with Windows 7 64 bit Windows Media Center and can get Clear QAM unencrypted cable channels? I've tried using a WinTV-HVR 950 which while compatible with Windows 7, could only play the analog channels due to their crummy drivers.

Yup. It recognized the tuner as analog but not the digital part. I tried to manually add it through media center as a digital tuner but it didn't work.
I have no problem with HDHomeRun network tuners and Win7 64-bit.
I'm currently running the HD Homerun dual tuner for digital and through in my old PVR-500 for analog on a win 7 64 system. The only issue with the PVR-500 was choppy playback. I found that it only works with less than 4gigs of memory. I have 4, had to go into msconfig and change memory from 4096 to 4095 and all works well now.
Any particular reason you need 64-bit? Just run Win7 32-bit and be done with it.
The prionciple reason for most users to run 64bit today is to have an operating system that runs fasster and that can move data faster. If you have applications that will run faster in more the 4GB oif memory then you should have 64bit since 32bit can not support an application using then more then 4GB of RAM. Of couse as indiividual applicastions are being converted to 64 bit they too will run faster on as 64bit system with a 64bit OS.
And an application that doesn't run at all in 64-bit runs 1000 times faster in 32-bit. It's called the right tool for the job.
For a media centric PC, you don't need 64-bit. When the time comes where all the drivers and applications catch up, then move to 64-bit. But I see no reason to bang your head against the wall if 32-bit works with no issues.

except that 64bit is slower and bigger (except when it isn't).
In a 64bit app, every variable a programmer uses now needs 64bits instead of 32 bits. This doubling of bit width means getting that information out of memory, or out of cache will take twice as long.
Even a app compiled explictly for 64bit won't neessacrily run faster.
64bit has 3 main advantages things:
-Expands the memory map beyond 2gb per process to 4gb even for 32bit apps, and goes to 64bit for native apps.
-Can do 64bit math in a single clock cylce.
-Doubles the number of registers available to the CPU per AMD's x64 extensions.
64bit has 2 main disadvatanges:
-drivers need to be rewritten for 64bit.
-Native 64bit pointers are twice as big as 32bit pointers and thus consume twice the memory and bandwidth to move around.
It's a trade off.
