Hi guys,

I've recently just built my own HTPC to compliment my new home theatre setup as well and have got the E6500 CPU along with the HD4350.

I've decided to keep my TV tuner card in my desktop for now so I can watch TV in my room, but in the future I may decide to get another card or move the current card to my HTPC.

It just so happened that my 4850 in my desktop died so I used my 4350 for a while before getting my new graphics card for the desktop.

What I found was that when I was watching TV3 there was a lot of lag and it would not play smoothly at all. Even though there weren't any glitches or green screens or any other problems. The CPU usage also did not increase by much when watching TV3.

So has anyone else who has a 4350 encountered similar problems, or is it something in my setup?

My desktop has E8200, with Nova 500 T, running Windows 7, PDVD 8 codec, Media Portal 1.1 beta, ATI driver version 10.3.

Would be great just to get some confirmation that it can definitely do TV3 without any lag so I know I didn't buy the wrong card.

Why don't you try with hardware acceleration off?
Your CPU should handle that fine (Pretty sure thats what I am running, I was playing 1080p @ 35 Mb/s with no hardware accel)

I never got good playback with an ATI with HA on, gave up and went to Nvidia - just worked.

Ah that's a good point, but still I would prefer to have it on and I feel its something to do with my setup since there's no reason why the 4350 can't do TV3

Actually, to do 1080i deinterlacing (TV3 in HD) using VA the minimum is a 4670 in the ATI 4XXX series.
Some 4650 cards could do the VA deinterlacing, but only ones with faster DDR3 memory running at a faster clock speed. Anything less will not deinterlace using VA (Vector Adaptive).

Not sure about the 5XXX series, I know the 5670 can definitely do VA, but not sure about the 5570 (any less can't apparently).

Yeah I thought that might be the case, but is it possible to just disable all deinterlacing? I don't really care about interlacing I just want a smooth output.

Have tried fiddling with the CCC settings btw but it didn't seem to make a difference to the lag.

Not sure as I don't own a 4350 sorry.

My Advice would be the settings in CCC:

For enabling Vector Adaptive: In Advanced View, look under AVIVO Video and then Basic Quality.

Turn that off, or turn off all deinterlacing and slowly add more.

Another thing may be your version of CCC, many people using the 4XXX series have stuck with 9.12 or 9.10/9.9 version of CCC because of issues with the 10 series. This is another option to try, just make sure to use CCleaner or another driver removal application after uninstalling the ATI drivers (and before you install new ones).

Ah yeah, I may try the 9 drivers, cause it definitely seems to be a driver issue to me.

You do realise you need to deinterlace the picture using either software or hardware deinterlacing? Hardware deinterlacing typically does do a better job.

Right, it looks like I have quite a few things to try at home now anyway. In another forum someone said that Aero might screw up the deinterlacing in ATI drivers.

Tbh I just want someone to come out and say they've got a 4350 and TV3 works fine for them so I have confirmation that the card is powerful enough for everything that I want to do.

oh dear! i bought mine 8600gt thinking it'll be fine but according to that article it wont do vector adaptive!

didnt realise you need such a super high end card to decode freeview! anyone knows how media centre decodes freeview? like how do you select VA vs MA vs etc?

Yeah its crazy eh how much you have to spend to get decent Freeview. I know plenty of gamers who run less powerful cards than the 4670 and here we are installing it in HTPCs seems like such a waste.

how does one know whether the 7 media centre is doing VA or MA etc?

An 8600GT works fine for Freeview. I've been using an 8500 GT for years and it does a fantastic job.

The problem with ATI is they've had continual ongoing issues with H.264 interlaced content and there problems have only recently been solved for most users. I wouldn't go anywhere near an ATI card for watching Freeview|HD in NZ.
