Hi, Thanks a lot for your help
There is a DirectShow setting for DV quality and it defualts to quarter resolution on some systems. The code for pix_movie tries to force the quality to the highest and that works in my testing.
Definitely sounds like that's my problem, or somehow related. It must be decoding at half or quarter resolution (I'd say half), so pix_movie's attempt to force the quality to the highest is failing in my case.
You can try to alter the default using the GraphEdit tool in the DirectShow SDK or find the registry value for it.
I'm not sure how to do that. I downloaded this application: http://www.digital-digest.com/dvd/downloads/graphedit.html I don't know if it is the graphedit you're talking about and whether it was already installed. Following the direction I found in a forum (http://forum.doom9.org/archive/index.php/t-34818.html) I've been able to "insert" a DirectShow DV Decoder filter, right-click on it / "properties". In the abovementioned forum post, it was claimed that just by selecting "full" as the resolution and doing apply and close, it would cause DirectShow to use that default with any application. I found the setting was already on "full". However, I did apply, but it had no effect on GEM. It still renders at reduced resolution.
By the way, both Virtual Dub and Windows Media Player decode DV files at full resolution and always did so on this machine.
I also tried to search for the key in the windows registry but had no luck. I searched for "DV" (too many matches: aDVanced etc etc), "DirectShow", "quality", but I didn't find it. Any clue?
Thanks a lot matteo
P.S. avis coded with PicVideo MJPEG with 1:1:1 subsampling are decoded fine, but if I code them with 4:2:2 subsampling, GEM crashes (closes PD without even opening the typical windows crash dialog) when trying to play them. -- Email.it, the professional e-mail, gratis per te: http://www.email.it/f

Do you have another DV codec installed? The settings for the MS are correct, but DirectShow could be using another codec.
I don't know about the PicVideo codec. I use ffdshow libavcodec for MJPEG which works pretty well.
