Reencoded without QPEL file won't play on DVP642

[howdy29]

I had a file that used QPEL. I used VirtualDub to reencode without the flag. Once done I used AVICHECK and it did not show QPEL. However, when I try to play it in my Phillips DVP642 the TV flashes different colors and then goes back to the menu. Also the time jumps by chunls forward until it gives up.

Anyone else experience this?

Never had a problem re-encoding QPEL files. I'd double-check your coding specs.

Be sure you finalized your DVD.

What codecs did you use for the new file? Be sure you didn't use too high a bitrate. Avoid VBR audio.

Is Global Motion Compensation (GMC) selected in the Xvid options (just below Qpel)? DVP642 doesn't like that option either.

Stick with the DXN Home Theatre profiles and you should be fine. No qpel, no gmc, vbv enabled and no CQM's.

Thanks for the suggestions. There is no GMC either. I ran it through AviCheck and there were no warnings (see below). I encoded the video with the exact same specs as the original with XVID. I direct stream copy of the audio.

I did finalize the DVD (two other files on the DVD work fine).

I was not aware of "DXN Home Theatre profiles". I will look around more to learn about them.

Just out of curiosity, what's the video bitrate?
My Philips 642 has issues w/video bitrate over 2000 with XviDs. Not a problem with DivX though.

[howdy29]

Avg bitrate is 1259.

Also, from VirtualDub the container format is "AVI-OpenDML".

BTW, this is the 2nd file I have tried to do this with and it happened with each of the files. I have 2 DVP642s and I get the same result on each of them.

Think going to DIVX would work better?

Have you tried just putting the avi on a CD instead of a DVD?

That bitrate is perfectly fine. With XviD, just keep it under 2000 for this player.

Are you burning your discs as Data discs? I've had no problems whether my AVI files are on DVDrs or CDrs just as long as they're burned as Data discs and finalized. (Also, I don't burn at top speed no matter what kind of discs they are)

My personal preference is to stick with DivX for this player but that's just me.

A couple of other variables could be coming into the situation here as well like bad discs or perhaps your burner needs a firmware upgrade...

[howdy29]

File is too large for a CD. These 2 converted QPEL files are the only problem ones I have had. The disc is fine as the other files work with no problem and these files work on a computer with no problem.

I do create the discs as a data disc using Nero.

*shrugs* I guess I can try DivX and see how that works. I just don't know why it wouldn't work.

Thanks again.

[somebodeez]

I don't know why else it wouldn't work either
If you do try DivX, make sure to use the Home Theater profile

[celtic_druid]

An XviD encode done with DXN HT profile should work just as well as a DivX encode done with DXN HT. Make sure that you are using a 1.1.x build of XviD not 1.0.x.

This should not be necessary the reason but your original file could be corrupted. Check if original avi file is not corrupted or is not corrupted while recoding. Recently I had a problem very closed to yours and finally found that the first frame of the avi file was broken.

Load the file into VirtualDub and just go forward by key frames clicking button at the bottom of VirtualDub window. Check the key frame numbers. Normally key frames are positioned far from each other like their numbers differ in hundreds. If you find something strange just remove that key frame and all the other normal frames that follows it until the next key frame.

The situation could be other then mine so I can't provide more precise guidance. In my case the numbers of key frames at the beginning of the file were like this
1,2,252,502,752 ...
So I suspected the frame 1 to be corrupted and removed it. Then I recoded the file to get rid of QPEL and my Philips then palyed it fine.

In my case there were no following normal frames after the broken key frame so I removed 1 only.

Optionally as an utmost cure just remove everything at the beginning of the file until the 1st good key frame VirtualDub can find. Hopefully the film will not be cut off too much at the beginning
Just mind that avi file should always start with the key frame.

The point is that PC software players can handle the situation and can probably just skip corrupted starting frames. While hardware player like Philips thing can't do that and reject the file completely.
