[mythtv] lockups with dual tuners again ... <sigh>

Okay, somewhere along the way of mucking about with btaudio and dual 
soundcards and dsp's, my dual tuner setup no longer works with mythtv.

If I set two concurrent shows to record in the epg or hit V for PiP, the 
machine now locks up tight.  Only way out is hitting the resert switch.  When 
it locks up, the caps lock and scroll lock keys both flash on and off about 
1hz.

I've checked the usual stuff, irq's etc. but no joy.  There have been no 
changes in hardware or relevant software since it did last work, other than 
module settings which shouldn't cause this problem.

The issue occurs under both custom kernels on my system: 2.4.18 (oss) and 
2.4.20 (alsa 0.9.0rc6).

I have an Aver TVPhone as my primary tv card and ATI TV Wonder as my 
secondary tuner.  The Aver card goes into line-in on my SB Live while the ATI 
card goes into the onboard VIA Motherboard line-in.  Mythtv is using /dev/dsp 
for the primary card and /dev/dsp2 for the secondary card.  Using Xawtv and 
sox, I can get the audio from the secondary TV card no problem.

My modules.conf and lsmod follow.
