Getting set up again, HD TV problems (1 Viewer)

[jmbillings]

Used to use MP a couple of years ago, switched to WMC as it was more reliable though. They seem to have stopped EPG updates now though, so trying MP again...

I've installed the latest beta, and initially had the HD TV codec on the Microsoft DTV decoder (assuming this was the same as WMC uses, which is fine) but it was bit "skippy", almost like watching something in fast forward with little jumps in picture.

I tried the new LAV options instead (ticking the DXVA2 option in setup) but it's awful - pauses for a second or two at a time, picture breaks up, MP gets quite unresponsive.

Any thoughts? I'm using the on-board ATI HD3200 graphics. As I say, WMC works fine for HD channels

The ATI HD3200 is more than capable of viewing smooth video.

Do you have the same issues if you record a show and watch that?

 

[jmbillings]

Cheers for the reply. I recorded a few minutes of BBC1 HD - playback is the same, very jerky, pausing for a second or two before jumping.

If I play back an MKV Bluray rip though, it plays back fine...?

Then it must be somewhere in your codecs. I don't have HD tv myself, but I guess you could try copying the codecs from the video section to the tv section.

And in the mean time, collect logs, and keep an eye on the CPU usage while testing.

Some logs attached, if useful...

At first glance, I don't see anything suspicious, but then again, I'm not a tv/codec expert.

I guess you'd better fill in your system specs, post a full debug log (http://wiki.team-mediaportal.com/Forum/How_to_post_logs) and call in some experts

1080i it is not, that is where the bottleneck is regarding jerky playback within MP for BBC HD, WMC seems to output a basic screen when playing these channels, no comparison to how the picture quality looks through LAV or Cyberlink filters.

BTW, you might want to try SAF6 unlocked, and select the Cyberlink filter for HDTV, I know it disables a lot of the video bells and whistles if the graphics processor is not up to it.

Ah, I seem to recall having to use SAF unlocked when I was last using MP, so you could be onto something there. Now I just need to find it again... :|

1080i it is not, ...

Don't you insult my graphics card

Just tested a 1080i movie on it, and it runs rather ok with cpu usage around 20%

No insult intended, my gt220 will not play HDTV smoothly neither, but seems to be fine with a 1080i file, so there is a difference
