I'm using a Zotac ION based system running Fedora FC14.<br>
<br>
At the moment I'm just trying to capture a recording and, as I<br>
understand things, system performance isn't an issue for that.<br>
<br>
If and when I manage to get something recorded I'll start worrying<br>
about being able to play it :-)<br>

<br>
Building the drivers wasn't hard because the script provided here<br>
<br>
<a href="http://git.linuxtv.org/media_build.git" target="_blank">http://git.linuxtv.org/media_build.git</a><br>
<br>
does it all.<br>
<br>
I had to install the kernel-devel package which meant kernel and<br>
nvidia updates. The script then asked for a couple of other packages<br>
and a perl module to be installed. Probably pretty straightforward if<br>
you know what you're doing, but it took me a while to figure out.<br>
<br>
The script builds loads of stuff as well as the cxd2820r driver, and<br>
took a while.<br>
<br>
#make install<br>
<br>
to install the drivers and, on a reboot the cxd2820r was automatically loaded.<br>
<br>
I'm running MythTv 0.24 fixes from a couple of weeks ago which I<br>
compiled myself, but wondering if I should be running trunk?<br>
<br>
In MythTV setup the 290e is detected both as a DVB device and as a V4L<br>
device. I chose DVB.<br>
<br>
I went through the rest of the setup and did a channel scan which<br>
found 65 DVB channels and 2 MPEG channels. I don't remember seeing<br>
MPEG channels before (could these be HD channels?)<br>
<br>
I downloaded some listing data from tv_grab_uk_rt. The DVB channels<br>
had callsigns and channel information in the database from the channel<br>
scan, the other two channels didn't so I fudged listing data for them<br>
copied from other channels.<br>
<br>
I started a frontend to tried and set up a recording...which is where<br>
things started to go wrong :-(<br>
<br>
I couldn't get a successful recording on any channel (I didn't try<br>
them all but I tried a few). The frontend displayed the recordings as<br>
"being tuned" rather than "being recorded". At first glance the<br>
backend log looked OK, with a "Started Recording" message, and no<br>
errors.<br>
<br>
<br>
Now it might just be I have a poor signal. I'm using the little<br>
spring thing that came with the USB tuner for the aerial. I'll move<br>
my test system tonight and plug it into my roof aerial.<br>
<br>
Otherwise I'm going to:<br>
<br>
1) Try the V4L option on the capture card setup.<br>
2) Enable more detailed logging on the backend<br>
3) Look up the transmitter parameters for Crystal Palace and look<br>
at the Transport settings in the database.<br>
4) Fiddle with the tuning parameters in mythtv-setup<br>
5) Do some more Googling<br>
<br>
Experience from others would definitely be useful.<br>
<br>
