G'day (Zoiks?)

Can't say much about "full uncompromised 1080i" as my previous
experience with MythTV is zero. I recently built a system to talk to
my Aquos LC-46PD7X, and as you're considering an Aquos I thought I'd
mention one problem: although the panel is 1920x1080 native, it will
NOT report that via the DVI connector - essentially I had to manually
create modelines for xorg, and force the nVidia drivers to ignore what
the TV was telling it.

As to nVidia vs. ATI - I purchased a Gigabyte AM2 board with onboard
HDMI thinking that would be the simplest, cheapest option, however I
could not get (with my limited knowledge and experience) any
satisfactory video playback and resorted to purchasing a fairly
low-end nVidia card, hopefully only until the open-source Radeon
drivers support video accelleration for my chipset.

That said, I find the playback via DVI indistinguishable from live TV
via the Aquos bult-in tuner. But I'm nearing 50 and thus going blind
so don't take my word as gospel!

AM2 5600+
2G Corsair cheap
500G SATA cheap
GA-MA69-S2H motherboard
Mythbuntu 7.10 upgraded to Myth 0.21 via Ubuntu packages
DviCo Dual-Digital 4

Good luck
