<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Hello, I've been building my Myth box for well over 3 moths now;
everything<br>
works except for one major problem, TV playback (lol).<br>
<br>
I find that TV playback with either no deinterlacing or non BOB<br>
deinterlacing just doesn't have enough frames a second to be watchable. For <br>
example, if you compare news tickers you get on sky news or BBC news, over<br>
normal Freeview / DVB-T, they are much smoother than through MythTV. Unless<br>
I can get the tickers to be as smooth as normal TV (or very close to), I'm <br>
gonna end up scrapping this project, something I really don't want to do.<br>
<br>
My setup is as follows, I have a Myth box running latest SVN build,<br>
outputting over DVI (from a Nvidia 6200 chipset) direct to my LCD TV. I <br>
haven't created a custom modeline, as I can get crisp, no overscanning<br>
output, using the resolution 1360x768, progressive. Now, the solution to a<br>
low frame rate is to use BOB deinterlacing, this makes TV smooth, but has <br>
some very horrible side effects.<o:p></o:p></span></font></p>

Is this live tv? if so, you should be aware that there is an issue with live tv
in svn that has resurfaced - probably dvb related. Playback is all over the
place until you pause and unpause - very noticeable for me and proving nigh on
impossible to track down.<br>
<br>
That aside, I've been working to get the same 'perfect' output for some time.
My solution was feeding my lcd tv 720x576i over the DVI connection (Samsung
LE32xxx). With BOB deinterlacing enabled the tv syncs with the incoming feed
and performs all the de-interlacing and image enhancement itself. Result -
picture quality almost indistinguishable from the tv's own dvb tuner. Tickers,
panning, sport - all perfectly smooth. I still get a slight 'bobbing' but
barely noticeable unless you're really looking for it. Even better, the tv
seems to do some buffering of its own internally and smooths out the smaller
glitches in playback.<br>
<br>
If you can get that up and running, the downsides are:-<br>
- interactive tv and osd display is lower quality due to the way the osd
is rendered onto a 'half' frame (unavoidable with bob)<br>
- gui runs at 720x576 (and is stretched - gui cannot handle non-square
pixels). You can use xrandr to avoid running the gui in this mode, but there
are issues with xrandr and aspect ratio at the moment.<br>
- you will get overscan but you get used to it quickly enough -
interactive, for example, actually expects some overscan.<br>
<br>
Once HD is fully functional, I'll start using xrandr to switch between 1080i,
576i etc but at the moment I'm happy with 576i. (and be aware - I have an
FX6200 as well - there is a bug (bugs!?) in the latest nvidia drivers that
prevent 1080i playback using xv/xvmc with certain settings. Cost me a large
chunk of last weekend to find that out...)<br>
