I'm in exactly the same boat as you! I've been using vdr for about 8 years 
now but only for SD stuff. I'm about to order a new hard disk (for a 
different machine) and was very tempted to add a nanoStick T2 290e to the 
order!

I'd be really interested to hear how youget on with the nanostick (the 
only info on it I can really find is at 
http://stevekerrison.com/290e/index.html: just had a quick look and he's 
updated it since I last looked! toried of reprogramming a broken nanostick 
and baking it in the oven!).

Is the driver now mainstream and, essentially, fully working? It looks 
like it should do. Sod it: just added one to my order! ;-)

I've been using xmltv for a while to grab epg data from the Radio Times 
xml streams. I'm sure they have dta for HD channels too. It also means you 
get 2 weeks' worth of data and lenghtier write-ups of films, etc.

What output device are you using for HD? I'm currently using softdevice 
(which I'm still hacking to get stable with current vdr versions) with a 
Matrox card for output using DirectFB. I'm just starting to investigate 
whether it's possible to use VDPAU to do the meaty decoding and then sent 
the decoded frames to DirectFB (i.e. no need for X to be running). I 
_think_ this is possible to do: svn avidemux can use VDPAU to offload 
decoding, apparently.

If that's not doable, I guess I'll build a new Ion-based box and use xine 
for output. The problem then is that you don't tend to get many PCI slots 
for DVB cards (well, not with the small Atom boards). Maybe I could just 
keep the current vdr box (2.66 MHz P4) and stick an Nvidia graphics card 
in it. Decisions decisions...

Cheers,

Laz
