In fact this is a MythDora installation. My guess was a kernel  
version/module mismatch as well, and I asked the developers about  
that, but they assure me that this is a straight Fedora Core 4  
installation, and that alsa is from the FC kernel.

Apparently a new FC4 kernel has just come out, and the system is  
going to be updated to that, which might correct the problem.

I DLed what was supposed to be the kernel sources for this kernel  
version for FC4 as I said, but this is what turned me off to RedHat  
years ago, you never really knew how things were compiled and they  
played games with the kernel sources that caused me a lot of  
problems. Why do they make you jump through hoops just to get the  
kernel sources. IMHO there should be *something* linked to /usr/src/ 
linux that I can go into, type "make", and get the very same kernel  
that I am running. For some reason RH does not seem to agree.

But I see a lot of folks running FC4, apparently happily, but I don't  
know how many might be using Plextors. The driver worked just fine on  
a gentoo 2.6.15 system. At least with Gentoo you *know* your sources  
match your executables.

I suppose I could just compile the kernel source tree and install it  
and its modules, but I'm afraid that might break some other kernel  
modules that comprise this system.

I must say, though, that I have tried a lot of distros and  
installation methods for MythTV, and MythDora has worked better than  
any others. Most things just plain work out of the box, things that I  
sweated for weeks to get even marginally working with other systems.  
Generating a DVD of a program with three mouse clicks from a web  
interface is pretty cool, and a working MediaMVP is about three lines  
of typing and it works. I must say it is a pretty good way to get a  
working 0.19 system with little pain.

I am impressed with 0.19, now that I have it mostly running. I really  
like the new live TV system, sort of like a browser history for TV.  
Kudos to all of the MythTV team that's put together a very nice  
system, once you get it working :-)

Thanks for the input.
