how far off are you guys for fixing the tsreader for h264?
1080i material not deinterlacing under 1.0.1.0 (1 Viewer)

It took me a while to find this thread, but when I did I realised why I was having problems with 1080i (TV3 here in NZ).
Previously, I had been using 1RC2 with an Nvidia 8500GT. This was because I could never get the onboard HD3200 to work. I recently moved to 1.0.2 and re-tried my onboard HD3200 (780g motherboard) with no luck under Win XP SP3 nor Vista 64-bit.
Because my NVidia lacked HDCP, I went a got a new Nvidia GT240-based card. Much to my surprise and real annoyance, this stuttered, just like the onboard HD3200 (under XP SP3). High Jitter scores.
I've just reverted to 1.0.0 (on XP SP3) and recordings and live TV are working flawlessly with the GT240. I suspect they will with the HD3200.
The trials and tribulations I have had over the last god knows how long with MP, ATI and effin Catalyst drivers has led me to think of throwing the damn rig out the window and buying a Tivo box or something on many occasions.
I'm sorry if I am racking up old stuff here but I can see no obvious benefit to the change done between 1.0.0 to 1.0.1. If PowerDVD can play 1080i well enough with an HD3200, why can't MP? It did/does with 1.0.0.

So you have a new GT240, which seems to be just a little shy of a 9800GT, and you still see problems? Wow, this is really looking more like a bug than a feature that the devs added.
The HD3200 has I believe 40 compute units, the GT240 has 96. Presumably your card has a 1Gb or at least 512Mb of GDDR. How much RAM is on your GT240?
I shelled out for a 4670 (300 compute units, 1Gb GDDR3) just to keep MP 1080i happy.

Your BE-2350 doesn't support HT3 - I've been told that's where my system falls short which is near identical (except I'm still using my 3200HD).
XFX GT-240X-ZNFA Geforce GT 240 1GB 128-bit GDDR3 PCI Express 2.0 x16. I tried sticking with NVidia because of previous issues ATI issues. Seems this is not enough. Well, not enough for MP 1.0.1 and above.
Your CPU is an Athlon X2 BE-2350 though right? What core? Brisbane?
My Athlon X2 5500+ is a Brisbane core and doesn't support HT3 either thus I have the same issues.
I'm not quite sure why HT3 is required in MediaPortal to (hardware) de-interlace 1080i given it works in other programs.
Yeah I know the CPU won't do HT3 - will that affect a separate video card? On a related note, perhaps the h/w requirements on the MP wiki should be updated to let people know what's required for 1080i after the 1.0.1 change.

I'm the OP of this thread and also have the AMD Athlon X2 BE-2350 Brisbane 2.1GHz 2 x 512KB L2 Cache Socket AM2 45W Dual-Core Processor. I am shocked to think the newer video cards perform worse than the N9500GT that got my rig running smooth again! I paid under $70 and it has 32 pipelines at 550MHz/512MB and passes my audio via HDMI too. I'd posted several links in this thread where the HD3200 was being compared and I think it may work with a higher grade CPU but the BE-2350 is a 2000MHz HT... I figured a video card was cost effective over buying a Phenom X4 for AM2+ socket which is becoming aged...
I must ask if the NVidia drivers you're running address your card? It makes no sense that a 240 would underperform my N9500GT! Are you trying to run dual-heads on the card? I had found years back that using dual-heads can effect video performance and have steered clear by running a single head and switching between profiles to switch the video between my projector and monitor.
How about your tuning/codec... I'm in the US but see you mention the .264 codec. I found the MPC-HC .264 utilizes DXVA and passes MOST of the processing to the video card dropping my BE-2350 from 50% to 5% during .264-encoded .mkv playback. Now that may not effect overall performance because I'm really just shifting the processing from the CPU to GPU, but it makes me feel better to see lower CPU utilization!
How about the PCI bus? These cards are for PCIe 2.0 and our AM2/AM2+mobos are PCIe 1.0 - we're counting on the cards working at slower clock speeds to provide ample performance. I don't think we can quite take advantage of the full specs stated, although I'm getting what I need for 1080i on my system, and the comparisons we're drawing should be relative... just a thought!
Tell us more... What codec do you use for your TV broadcast (or recorded TV playback)? How is your CPU utilization? Dual-heads in use on the Video card? What version video driver are you using? What resolution are you running? (I'm running 1280x720p out my HDMI.) Does anyone know if this 240X card is a 'reduced' version of the base 240, or may be limited somehow for a lower selling price? Just asking so maybe we can figure why your new 240X isn't adding up to clean video!
