Hi Steven,<br>
<br>
For the 'picture in picture' effect issue, disable the MHEG support for
now. From my research and experimentation, there is a bug in the MHEG
support which is due to the rendering code trying to allocate/draw the
received content into a buffer. Sometimes this fails, and there is a
second buffer (erroneously) created, leading to the picture in picture
effect. I haven't been able to see how/why this happens (no real time
to debug), but simply disabling it solves the problem. Who needs to
know the Lotto number results anyways? (30 million and counting ...
yikes!).<br>
<br>
I'm about to do a full rebuild of my Core 2 Duo E7200 (and an E8400)
system this weekend with Ubuntu 8.04.1 and Paul's patches - maybe
adding some extra 'juice' with some performance related code changes
I'd previously done, and see how it all goes. Using the E7200 I've been
able to watch TV3 with my own loop filter patches quite happily
(barring the front-end crashing - *grumble*), without stutter and
otherwise without issues.<br>
<br>
I'd already done the same as you have, limiting the frequency
scaling/governor to prevent stuttering from the load switching CPU
cores and frequencies. I found that this already helped markedly in
keeping the performance constant. Also I'd set up the processing, and
de-interlacing as I'd specified in a post I made earlier - combination
system with analog and DVB-T, patched/updated v4l drivers, and all that
is working well.<br>
<br>
I'm using an Abit I-N73H HDMI GeForce7100 (nForce 630i) Motherboard
($110 is the cheapest on PriceSpy), and a friend is using the
comparable Asus version. Being a fully integrated solution, it works
quite well, and I've had few (if any) issues with it. Video performance
is excellent (given no H.264 hardware assisted acceleration anyways),
HDMI, D-Sub, Optical SP/DIF, 7.1 Channel Audio, and the performance of
the board/chipset itself can't be beat for the price.<br>
<br>

<br>
Granted, this is an inexpensive solution, but the only thing it doesn't
have which you want is Composite/Component/S-Video ... which
potentially could be served by either a D-Sub converter (hack), or by
using a different nVidia card with built-in Video Out, since the
motherboard has a PCI-E x 16 slot available.<br>
<br>

<div>Ok so a lot more speeds to play with but for the purposes of

its fastest speed.</div>

<div>2. Occasionally I get a picture in picture effect when I switch
between 720p and 1080i channels which I have two copies of the same
video feed on screen, one of which is in a small box in the top left
hand of the screen.</div>

<div>So I have something that works, but I wouldn't consider it
customer ready.</div>

<div>I think I need to consider an Intel compatible alternative, but
can't find a board with integrated Composite/Component/SVideo as well
as DVI/HDMI in the Intel space.</div>
