I have a very strange issue that I've been troubleshooting all last night. I'm not sure exactly where to post, so I'll post here and hope I can try and get some answers to my problem.

The short of the story is, Mediaportal doesn't seem to be respecting the codecs and rendering them the same way as WMP/any DirectX app does outside of mediaportal. In my case, this is causing scaling artifacts (jagged edges) and deinterlacing issues.

In more detail, when watching DVD or tv shows ripped from DVD (vob files converted to mpgs), I get horrible scaling and no deinterlacing. However playing the same DVD and mpg files back using graphedit/WMP/PowerDVD renders the video beautifully - no jaggies, nicely deinterlaced.

I've had this problem for a while - I just thought I didn't have a good mpeg2 decoder, so last night I installed PowerDVD to solve the issue. The end result is I could never get a good render in Mediaportal even after removing every single mpeg2 codec on my system so that only "Cyberlink PDVD7/SP" is the only one left.

I spent quite a bit of time ensuring the merits were correct so when graphedit renders vob and mpeg files, the filters used are correct (Cyberlink as the video decoder).

However it's been for no success so far - DVDs and mpg files look like crap in MediaPortal.

Checking the log files shows that it does seem to be adding the correct filters (ac3filter for audio and cyberlink PDVD7 for video), but there is the addition of a TSFileSource filter and I'm not clear what its role is.

I'm really stumped now. Merits shouldn't be the problem - there is only one mpeg decoder registered. Mediaportal reports that it is using the correct filters. The only thing I can think of is Mediaportal isn't respecting the non-DXVA request - so all decoding is being done by hardware?

The thing that stumps me most is rendering an mpg outside of mediaportal either in powerdvd, wmp or through graphedit, the resulting video looks great!

Help!

I have done a bit more investigation into this issue this afternoon.

It seems as though Mediaportal is reporting the width and height of the video wrongly. This would explain the scaling issues.

The detailed log is below, however here is an excerpt highlighting what is happening:

2007-06-22 17:44:45.343750 [Info.][19]: PlaneScene: video WxH  : 853x480
2007-06-22 17:44:45.343750 [Info.][19]: PlaneScene: video AR   : 853:480

2007-06-22 17:44:45.343750 [Info.][19]: PlaneScene: AR type    : Normal

2007-06-22 17:44:45.343750 [Info.][19]: PlaneScene: dst        : (0,1)-(1360,766)

However, gspot correctly reports the video dimensions as 720x480.

Incidentally, playing back an mkv file and checking the logs shows that MP correctly reports the dimensions (1280x720).

I wonder why the vob/mpgs are being reported incorrectly?? Would it be the tsfilesource filter?
