Aliasing and stuttering issues on HD source

Hello,

My source is 1080i25 music video capture. Using Srestore() solved the interlacing and filed-blends issues, but now there's a stutter caused by what seems to be dupe frames. Worse then the stuttering, there's some very bad aliasing I couldn't get rid of, no matter what I tried.

Here are samples of aliasing and stuttering from the unprocessed source (TS files) + same samples processed with the script below and encoded to Xvid (Avi):
http://www.mediafire.com/?zugnugj3mzd (26 MB).

Script:
Code:
DSS2("D:\HDTV.ts")
AssumeTFF()
tdeint(mode=1)
srestore()
Any advice on these issues? I'm out of ideas

Actually, this "aliasing" problem is so bad, that I'm not sure I can call it aliasing anymore. Another thing is that this artifact is not on every frame, but appears in an alternately fashion.
here it is:

Link is under "Mediafire" in the first post. I'll edit it to make it more clear.

Hmh. Quickly looking at the source, you might want to ask MTV if they destroyed the clip on purpose, or if they're simply incompetent.

Off hand, I see no way.

Fact is (seems to be) that they took already-fieldblended SD crappola, and just blew it up to HD res. I'm not sure if the upscale even was done correctly. I quickly tried to re-downscale it to interlaced SD, but that still looks quite messy. Personally, I would not invest much time into that. Label it "FUBAR", and let it be.

I was afraid you were going to say that...
Anyway, is there any clue on what might have caused this "mega-aliasing"?

Sorry I can't add a lot more other than: "UNBELIEVABLE". The most stupid part is the huge burned-in "MTV HD" ("HD"????) logo!

The actual meaning of "HD" is case dependent. It can stand for "High Definition". But it can also mean "Huge Disappointment", or "Hilarious Disaster", ...

(for the wordsmiths: any way to make "empty promises" fit to the letters h+d? Or something with "scam" or similar?)

"Hollow" for "empty" comes to mind, but "promises" is a toughy...

How about "humongous deception"?

Here's another case of "Hilarious Disaster":
http://www.lyris-lite.net/2009/12/26...ray-disc-ever/

For those who don't want to hit the link: a Blu-ray Disc with an upconverted SD transfer which isn't even acceptable by SD standards.
