Please help me, I am tired of finding what this problem is!!

I am using Premier Pro to compile some slideshows with music, my plan is to get as many pictures on a dvd as possible and include menu's. I have no problem with premier setting up the project, my settings are

re size jpg's to 720*534 and save a bmp's
bring into storeyboard after changing default timings to 7 seconds
export to timeline and bring in audio file
also use transitions between clips
encode to disc, these are my settings;

Video Summary:
Codec: MainConcept MPEG Video
Quality: 5.00 (high quality)
TV Standard: PAL
Aspect Ratio: 4:3
Frame Rate: 25 fps
Program Sequence: Progressive
Bitrate Encoding: VBR
Encoding Passes: Two
Target Bitrate (Mbps): 6.0000 (medium quality)
Maximum Bitrate (Mbps): 9.0000 (high quality)
Minimum Bitrate (Mbps): 4.0000 (low quality)
M Frames: 3
N Frames: 15

Audio Summary:
Codec: PCM Audio
Sample Rate: 48 kHz

Multiplexer Summary:
Multiplexing Type: None

Then i use dvd lab to create the menu's and then mux the files to disc and burn with nero

When viewed on my standalone tv the majority of the stills flicker which in some cases is intolerable. I have tried other settings in Premier to try to remove this flicker but to date have had no luck, the strange thing is though, if I use DV Lab to create a slideshow using the same images (without audio) and mux them and burn with nero the quality is fine therefore i reckon the problem is somewhere within Premier.

The project settings for the slideshow are set as this;

Pixel aspect ratio D1/DV Pal
25fps Timecode
No fields (progressive scan)

Large beer to who can kill this one for me.
