Aaargh, forgot to change the vdr Digest from the subject to something reasonable... sorry about the noise... Here's the same with a bit more identifiable subject.
You forgot to correct the In-Reply-To header. ;-)

I'm inclined to believe the latter: you keep forgetting. :-)
Well, I'd put the header problem somewhere between "didn't even think of it" and "can't do it with my emailer" (at least after a quick check and a couple of attempts), sorry...
although not perfectly (rapid motion, such as news tickers, are jumpy with xxmc on openchrome when HW acceleration is on, not sure why)
Sounds like an X problem to me, though it could just possibly be to do with xine-lib's xxmc support.
Yes, could be an X (openchrome) problem, could be xxmc or the HW decoding, I'm a bit at loss with it at the moment. With Xv the quality is just fine (but CPU at around 60-70%, a bit too touchy for other activity). The xxmc is somewhat blurry and jumping a bit with the tickers, with CPU at 30%. Any similar experience/solutions anyone? The hardware is CN700 (EPIA EN-12000).
Well, maybe I should actually start another thread on this (with proper headers on the replys :-) ), or maybe at openchrome or xine...
So (wrote he hoping), would things get better (regarding my quality problems) if I changed to 1.1.2?
Hopefully not ? unless you mean 1.2, in which case you'll see much the same as 1.1 hg wrt xxmc.
I was (not really that optimistically) thinking that maybe the <<1.1.3 meant something horrible happens at higher versions... but I wasn't really expecting a positive answer on that. And it does seem that not much has happened with xine xxmc recently.
Basically, if you upgrade xine-lib to a newer ABI-compatible version, you won't need to rebuild plugins (except just the once to get them using the new plugin directory naming scheme when you upgrade past 1.1.10.1).
Ok, thanks for the info, maybe I'll try a newer version at some stage...

All XvMC implementations that I know of have poor deinterlacing, which makes them pretty useless for decoding interlaced video. Your description suggests that openchrome just drops the other field, so you lose half of both the vertical resolution and temporal definition (50 fields/s -> 25 frames/s). Continuous small skips (at regular or seemingly random intervals) could also be caused by a refresh-rate mismatch, but if Xv is ok, this is not the main problem in your case.
