This question might be a bit off-topic for this forum, so apologies in advance.

I have an video file copied off a PVR.  It's MPEG2 format 4:3 anamorphic.

I've been trying to work out if its possible to get this file to play automatically in WS without resampling it at WS resolution.
Do any of the stream or transport formats support such a flag, or is the only option to resample?

I've been playing around, for instance, with the anamorphic setting in Handbrake, but that doesn't seem to do anything.  Or at least none of the players I've tried (VLC, MPC, WMP) play it as anything other than 4:3 (unless I manually change the playert to 16:9).

with something like VideoReDo, you can alter the resolution, without re-coding it.  It is awesome for editing MPEG2 files, and is well worth the US$35 (or so) is costs.

Not sure if that's what you mean.

Actually, I think I could have asked that question better...

I want to recompress this video to H.264 or divx (it's very large atm).  Are there any formats that support an anamorphic flag in the stream, if so which?  And what's the best tool to compress and/or set this flag?

I was presuming that streams would support the flag for efficiency sakes. But if the answer is they don't, then I know I have to resample at the correct resolution.

Handbrake has an 'anamorphic' option on the compression screen, for example, but it doesn't seem to do what I expected it would.

I have made anamorphic h264 in aftereffects before. Quicktime being the polished turd of software it is ignored it and showed as 4:3 - VLC correctly played it in the correct apsect. It was in a .mp4 container. Just happened so I have no idea how it signaled it.

I was on a mac so couldnt try media player classic with the file. I dont know if its in the h264 or the container to signal it, but it definatly can be done.
