[Mvpmc-devel] Mpeg playback display size not working correctly... help needed

[Malcolm S. <ma...@po...>]

Hi

I'm having problems trying to get the display size sorted on the MVP. I 
have 2 recording sources on my myth box,
1. PVR 250 connected to a cable box via composite
2. Nova-t (DVB terrristrial card)

The playback for the Nova t (video source 4 below), plays fine... fits 
the screen perfectly in either 4:3 / 16:9 mode.

When I playback stuff from the PVR 250 (set to record resolution of 
720x576) the picture is displayed with only about the central 500 
pixels, leaving the rest on the outside of the screen.

What am I doing wrong?

Two sample outputs are below... I've included the MVP output and a copy 
of the output from tcprobe for both. The first is the PVR (bad one) and 
the second the Nova -t (working one).

The only differences I can see is one is program stream (PS) and the 
other a PES...

I can post pictures / files if anyone needs more info.

Many thanks
