<div>Hi all,<br><br>Before I ask my question let me list my current setup: (Skip to the bottom paragraph for the main question)<br><br><strong><u>MythTV Box (Dual frontend/backend)<br></u>Motherboard:</strong> MSI K8NGM2-FID
<br><strong>CPU:</strong> AMD 3700+<br><strong>
GFX Card:</strong> nVidia 6150, onboard, with DVI, AGP, Component, & Composite out<br><strong>HDD:</strong> 1x SATA 200Gb</div>
<div> </div>
<div><strong><u>TV</u></strong></div>
<div><strong>Type: </strong>LCD</div>
<div><strong>Model: </strong>LG 37LP1D</div>
<div><strong>Inputs: </strong>DVI (PC), DVI (TV), Componet, HDMI<br><span style="font-weight: bold;">Working Modelines: </span>1280x720p, at 50Hz with a little overscan<br></div>
<div> </div>
<div>Basically, I've been working on this box since Easter. I've had lots of problems, including driver bugs for the graphics card, bios bugs (still having problems), problems with my VFD & Remote, etc...</div>

<div>My main problem was TV playback. I had my TV set on 'DVI (PC)', and the EDID information passed let me get a picture with no overscan whatsoever. The drawback with this was that it was dropping frames (badly, don't know why, just TV is unwatchable). TV was jerky, (especially the news tickers). I eventually switched to DVI (TV), but had many problems getting a working setup (custom modeline,
<a href="http://X.org" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">X.org</a> settings etc..). However, with much tinkering I now have a working display (operating at the above posted modeline). My problem is deinterlacing:
<br><br>I've found that I just can't match the quality of TV from my freeview STB. I've gone through all the deinterlacing methods, and the only one that has a decent framerate is BOB. However, I find that BOB causes some parts of the picture to flicker. Normal scenes look fine, but when digital boxes are drawn on the screen (such as a news ticker), the horizontal edges between the box and the rest of the picture will flicker slightly. It's a bit hard to explain, but is most noticeable when a static picture is displayed. The whole picture isn't jumping (like when there is a refresh rate mismatch), just objects which are perfectly horizontal flicker (and is bit annoying).
I also oversize the picture slightly to get rid of the top and bottom lines from flickering<br><br>People have told me that you can get perfect TV using Kernel deinterlacing, with a framerate that's as good as standard TV (and doesn't have any flicker), however for me this method just doesn't have enough FPS.
<br><br>I don't know whether my problems are related to an incorrect setup (using Gentoo), buggy hardware, or just my incompetence, but could someone tell me what I *should* get from each of the deinterlacing methods, as I've never had anything to compare too!
<br><br>Thanks in advance, James<br><br>P.S. Sorry for the long post...<br></div>
