I'm trying to get widescreen switching working and I was wondering if anyone had successfully got this working for PAL on a 350?
Several months ago, I tried to get this working using the 0.2 driver on my Panasonic TV. When trying 'ivtvctl -x 1 -b wss -x wss', my TV would interpret some switching signals and go into anamorphic widescreen mode, but it wasn't stable, switching back and forth every few seconds. Additionally, I would see patches of blocking artifacts in the video every now and again. The feed was a direct composite connection from my digital cable box. Now I'm using 0.3.7a + Bryan's audio backout patch. If I try 'ivtvctl -x 1 -b wss -x wss', I see no blocking artifacts but I also see no widescreen switching at all. To add to the mix, I've also changed the feed; output from the cable box is now going through an RGB->svideo convertor before hitting the 350. I tried using the wss.c sample program within utilities and this switches my TV from 4:3 to 16:9 centered zoom. After looking at the sources, I changed it to switch from 4:3 to anamorphic 16:9, ie. only horizontal expansion and it works just fine. Am I missing a piece of the jigsaw to get this working automatically or is it just plain impossible? As I write this, I'm beginning to wonder if the RGB->svideo convertor may be stripping content from the VBI...
