My old system used to be a 1 GHz Athlon with a dxr3 in it and it was rock 
solid most of the time. The system did sometimes fail to boot but I 
eventually tracked that down to a dodgy PSU. I changed this for my 
current Via Epia system because the Athlon made lots of noise!

Softdevice also gives a much better OSD than the dxr3.

I replaced the dxr3 with a G450 and moved that system upstairs to use with 
streamdev and an nfs-mounted /video directory. After a little bit of 
fiddling with kernel patches and making an RGB component cable, the 
picture was perfect.

However, since I upgraded softdevice a few weeks back, interlaced streams 
tend to judder a bit on the G450, and the video gets jerky when the OSD 
is displayed. :(

Bizarrely, if I move the 'cursor' down a menu by holding down a key, I get 
a weird ghosting trail of the cursor, i.e. it fades out behind it as it 
moves. I presume it isn't meant to do this (doesn't on my Epia system) 
but it looks quite cool!

I'm sure softdevice was perfect with interlaced streams before the upgrade 
(it has been kept quite up to date with softdevice CVS so it must be 
something recent). I haven't looked into this yet but suspect something 
has changed with the mgatv option (triple buffering enabled or disabled 
or something?).

As you say, softplay is a great, simple solution without needing mplayer 
running too! Shame I don't get sound from RealMedia files!
