DVD is ALWAYS SDef only, 720x480, 60i
the max bit-rate of a disk is 9.somewhat mbps - which isn't that much for mp2
Your material comes highly-compressed into FCPX, although the Pana700 offers superb 28mbps max bitrate. When your recordings are not within its 'best range' , e.g. has a way too high dynamic range, or low light condition, or … , the original mts probably looks good on playback, but in step #2, processing + encoding on export/transcoding to disk, any (invisible) compression flaws get multiplied .....
for usage with iDVD there's only one advice:
export the original Project/cmd-E to avoid useless, lossy 'inbetweens' and keep the project under 60min, to trigger iDVD using the max bitrate. (the benchmarks are <60=9mbps, <90min=6mbps, <120min=4mbps)
.... that's two advices? ....

Thank you for your input. Using cmd-E is I understand the same as the File->Share->Master route I take and my project is well below 60 minutes. Am I right in understanding then that what I am doing is a reasonable aproach? I just don't see whay I should get the patches of image "shimmer" on the final DVD. Do the sort of settings I'm using for producing my master file look Ok? Certainly the master file produced by exporting from FCPX looks great, it's what iDVD seems to do that degrades things
Thank you again.

a) I would import straight from camcorder - the way thru ClipWrap is only needed for 'orphanized' mts = without its full AVCHD-structure ... but ClipWrap doesn'tdo no harm ... just waste of time.-
b) as mentioned: the biggest fails happened on recording! an underexposured, amplified low-light video looks probably good on first sight, but ANY conversion process will brutally show its imperfection.
c) your files come in as h.264, get transformed into the intermediate proRes and finally HAVE to be converted again into mp2 ... which is far from perfect.
example: a dark in-room scenery, 'natural' light, shadows (high in-cam amplification, ASA3200 etc) ... there ARE artefacts on recording I promise; in final step, this pic gets a) scaled, b) that 'random noise' has to be differed from black cat Felix, coming from under the couch = a dumb compressor isn't able to make such a differentiation. professional material is optimized in dynamic range, peeks (are you using scopes in FCPX?), color dynamics, noise reduced etc etc ....
I'm afraid, your 'shimmer' (artefacts, banding, noise) has no single-click-solution ...........
aside better cinematography ...
with superb input, iDVD does a great job!
