OK, thanks for the info, this is starting to make a bit more sense now:

@mythbox:~$ cat /proc/cpuinfo
processor       : 0
vendor_id       : AuthenticAMD
cpu family      : 15
model           : 4
model name      : AMD Athlon(tm) 64 Processor 3000+
stepping        : 8
cpu MHz         : 800.000
cache size      : 512 KB
fpu             : yes
fpu_exception   : yes
cpuid level     : 1
wp              : yes
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca
cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext lm 3dnowext 3dnow

bogomips        : 1601.72
TLB size        : 1024 4K pages
clflush size    : 64
cache_alignment : 64
address sizes   : 40 bits physical, 48 bits virtual
power management: ts fid vid ttp

And when I play my HD test file, the CPU Mhz goes up to 2000.000.  So I
guess that means my machine is capable of 2 Ghz.

So, this machine "should" be able to display 720p using xvmc and bob
de-interlacing, if I am reading the chart on the wiki correctly (thank you
to the person who pointed me to that)!

But, I am stll confused as to why it  won't play the output from the HDTV
card.  It looks like my HD test file, which as I mentioned plays
beautifully, is 1080 (again, assuming I'm interpreting this right).  Here is
the relevant-looking part of what mplayer says when I play it:

Playing Elephants_Dream_HD.avi.

So why does mplayer do great with this, but Myth croaks on the QAM feed?

Thanks again, in advance,
Mary
