720p 1080i Issues on Xbox
#1
I've been using a component/HD cable on my soft modded (XBMC) Xbox for the past few years and it's been great. This is a v1.6 xbox, it can run all modes without any issues.

I recently tried the same cable on an exact same modded xbox v1.1 and although it works, whenever I switch to 480/720/1080 I get 2 lines of flashing black and white pixels.

I've researched this issue to death and can't find a viable solution beyond trying another cable. The cable still works fine on the v1.6 xbox.

I think I recall, a long time ago, reading about video issues using a v1.1 Xbox. I noticed one uses CONEXTANT? whilst the other uses EXCALIBUR. Is it simply that v1.1 can't handle the componen/hd output?

What other options do I have for getting HD quality on my v1.1 xbox? VGA cable?

Any direct links to products appreciated. Or any reasons why I'm receving the pixel lines appreciated.

This might not be what you want to hear but I have an xbox 1.0 which uses the Connexant encoder chip and can run 720p / 1080i with no problems.
It sounds like your cable is flaky and just doesn't like the other chips. Is it a genuine Microsoft cable?

Nope, not official one. Came recommended from here a long time ago. Can't be the cable, as I stated earlier, it works fine on 2 other xboes, only difference is their v1.6. Also, on v1.1 it works fine in all modes except the HD ones.

Maybe it has to do with how you switched the Xbox to NTSC?!

I'm using TECH's XBMC
XBMC4Xbox r29407 (Compiled Apr 27 2010)

I used the method you linked to change to NTSC. Everything as far as the guide is concerned worked fine, NTSC enabled in XBMC and MS Dash etc..

This is the issue

That's in HD skin (PM3 HD), but it's the same in PMIII skin. I basically have 2 of those lines which flash horizontally across the screen very quickly giving the effect of many flashing pixels.

Video Info on v1.1 xbox

Video Encoder: CONNEXANT
Screen Res: 1280x720 720p 16:9 60.00Hz
A/V Cable: HDTV
Video & XBE Region: NTSC M, Europe / Australia

The cable I'm using is a Bigben Interactive Component Cable. Took me awhile to find but this is it

Ok, I just went back on my v1.6 xbox and the video info, in contrast to v1.1 was this

Video Encoder: XCALIBUR
Screen Resolution: 1280x720 720p 16:9 60.00Hz
A/V Cable: HDTV
Video & XBE region: PAL I, Europe / Australia

As v1.6 is saying PAL I went into the MS Dash, all HD modes are enabled in it. Not sure why it says PAL when v1.1 says NTSC. In XBMC for both v1.1 and v1.6 going through the video modes shows NTSC on both not PAL, so dunno why the video info on v1.6 says PAL I.
