Mediaportal TV stuttering (1 Viewer)

[KOEZE]

Hello,

Been reading a lot these days. I'm building a budget system HTPC for HD display. The system as it is now is temporary in terms of the case (midi tower), supply (350W i had lying around) and harddisk (80GB IDE).

Main components:
Windows XP Pro SP3 fresh install
Abit Fatal1ty f-i90hd Mainboard (Ati X1250 with integrated HDMI)
Intel Dual Core E2180 (2Ghz)
2GB 800mhz memory
Firewire card with 3 connectors on the outside + 1 inside
FloppyDTV DVB-T tuner card.

Yet to come:

Antec Fusion Remote case
1TB Harddisk SATA
Philips USB receiver for remotecontrol
Reprogramming my Harmony 525 remote
Blu Ray combi drive

I have installed the Catalyst 7.2 drivers as recommended and the FloppyDTV drivers. Firmware is the latest. All Windows XP updates are there including WMP11.

FireDTV viewer has good TV quality.

I then installed Mediaportal with all settings default with a Mysql TV Server and made all settings as described in the post install readme.
All items work, including MyTV but it is completely unwatchable due to stuttering. A couple of frames every two seconds or something. I have tried recording and then playing (as I have read here that timeshifting could improve the qualitity) but the results are the same.

I hope someone can help out.

I have the same problem. I am using the inbuilt TV Engine and have set timeshifting to always be active and it has made TV OK. Have u tried activating the timeshifting button on the TV screen?

If it works you can then go into configuration to set timeshifting to always run.

where is the setting to have timeshifting alway running?

KOEZE - Quite a lengthy thread, but it might be worth your while to read and try the RelaxTsReaderForBadReception.txt.

Nato - only aplicable to older inbuilt TV. Are you using it or are you using TVServer like koeze? You also replied in the thread I linked to above. Any luck with RelaxTsReaderForBadReception.txt?

Yes so far it has gotten rid of the major stutter now just trying to iron out the little (minor) stutter . (Thanks For asking )

KOEZE, sorry I missed that you had the TVServer set up.

I have just fixed my issues on MP TV Client connecting to a seperate TV Server. There are many issues that may be unique to Australia. Some being, depending on broadcaster, lost audio and various incompatibilities between our DVB broadcasts and MP.

What I have found is that using Cyberlink 7 for audio has resolved all stuttering and seeking problems in the server timeshift buffer(this appears as channel change problems). However, the Cyberlink audio codec will not function correctly if spdif is set as the output. Also if AC3Filter is installed I need to have it's system setting set to "prefer AC3Filter" - this doesn't really make sense, and I have also unselected "Use AC3 Filter for" AC3 and Mpeg so that under Directshow other filters should be allowed for those formats.

The Cyberlink audio codec has added 1 to 2 seconds to channel changes but it has not missed a beat so far. Some filters seem to get confused and treat some AC3 streams as Mpeg audio. The Cyberlink codec seems to do it's own checking of the audio.

In my case I have gone back to Windows Media Player 10, but apparently MP does not actually require WMP for TV so this may not make a difference.

Anyway this gives you something else to try.

Generaly its not recomended to use Cyberlink audio codec for live TV. It has few issues that almost all team members have seen (and a lot of different people in the forum). (freeze after zapping, not able to decode audio on some channels etc.)

Much better audio codecs for the tv use are Microsoft's audio codec that comes with Vista or ffdshow audio codec.

My problem is, that as soon as i install ffdshow (even disabling it for all videotypes, only enabling for audio), it breaks my HW-acceleration of the pdvd-videocodec. After deinstalling ffdshow, HWA is back. So I am using MPA instead (XPsp3), that is coming with MP...

As sceptic as I was trying to solve my extensive stuttering problems in MP by just adding an empty text file, it worked like a charm. Picture is as good as my non amplified antenna can make it I guess.

Thanks a lot.
