Unfortunately I haven't found a source for Czech and Slovak guides either, but I thought that you've got some better sources than I do.
BTW looks I can't use the & on its own in XML (I didn't know that). The thing's working fine now, however half of the listings are missing i.e. they show up in the list, but if I select them and click OK nothing happens. So can't you split the Hungarian feed at least in two parts which would include (at least some partial) listing for all the programs? You could just post the new feed URLs in here so you don't have to upload a new package.
