Can anybody confirm jamming (sometimes showing old frames so that video seems to play backwards for a moment resulting in very jerky playback) and lockups (cycling between two sequential frames infinitely) on high resolution widescreen movies with '-vo xv' video output (or "vo = xv" in /home/user/.mplayer/config)?
I tried two of such movies and both failed to play properly:
1. 512x288 23.976 fps 838.2 kbps
2. 640x360 23.976 fps 839.9 kbps
Both of them played just file with the previous firmware and '-vo nokia770' video output. Can you see anything like this or I'm the one unlucky here?

I would be glad to switch to xv, but this problem will have to be fixed. Otherwise it defeats the purpose of having mplayer installed on the device - to watch normal nonconverted divx/xvid movies.

Now I'm waiting for the kernel and xserver sources of the new firmware to become available in order to see what can be done.
