4:3 mpeg4

[rx5670]

Hello!
I watch 36E (HTB+)
After I start my solo2 from deep standby or after I reboot it, 4:3 mpeg4 channels looks stretched horizontally. If I switch to 4:3 mpeg2 and then back to 4:3 mpeg4, it looks good.
I prefer pan&scan for 4:3 channels when no black zones on the sides and no deformations of the picture.
Switching aspect ratio by long green button works well.

Thanks.
