After days of messing around with all possible combinations to encode a few minute DV source to MPEG-2 in 2.5, I've finally found the solution: 3.0 XPress.

In 2.5, I set a GOP of I=1 P=14 B=0 MAX=18. All sizes are 4:3 (720x480) NTSC. 10bits, CBR8000, everything else set just like in your guide. Unfortunately, the finished product was crap on both my TV and computer. The image was extremely blocky and pixelated, and looked liked a blown up 320x240 MPEG-1.

I then tried all the (relatively) same settings in 3.0 XPress and... WOW, I never thought the video could look so good.

The changes are so drastic that I'm sure there must be a problem with my version of 2.5, but I couldn't track it down. I used 3.0 with the following settings (note the field order is Top -- weird, eh?):

The field order is weird indeed. Have you played the result on a set-top player? How was the source captured? Via a regular OHCI IEEE-1394 card / port, or using some "fancy" card (Matrox, Canopus, etc., with real-time effects)?

As to your problems with 2.5, did you try a different VFAPI loader (ex., raising or lowering the DirectShow loader's priority)? The problem could be with the DV codec, not TMPGEnc itself (ex., multiple DV codecs in the system, and TMPGEnc 2.5 using the wrong one - I think 2.5 defaults to VFW, while Xpress defaults to DirectShow).

How could I find out what codec the system uses?
And how would I change this if necessary?

If you have GSpot or VirtualDub, etc., you should be able to see a list of installed codecs. You can also get a list in Control Panel (Sound and Audio Devices -> Hardware -> Video Codecs -> Properties), but I think some codecs won't show up here.

Most 3rd party codecs should be uninstallable via Windows' Control Panel. If they are not present in the "Add or Remove Programs" section, you can go to the place I described above (Sound and Audio Devices -> Hardware -> Video Codecs -> Properties), select them, and click on "remove".
