Just some related information first, that may be helpful to know...
In iTunes, you can categorize those converted podcast episodes as podcast (not music). Select the podcast (or a set of podcasts) currently categorized as Music (in iTunes) and do a Get Info. On the Info window, go to the Options tab. Change Media Kind from Music to Podcast. Those podcasts should now appear in iTunes as podcasts.
Even with an iPod nano, you can create a playlist and put podcast episodes on the playlist in any desired playlist order. You can also "mix and match" podcast episodes from different podcasts. Sync that playlist to your iPod nano. You can then play that playlist in your car.
For the described problem, if this only happens with those BBC podcasts, there may be something unusual about those files that causes the problem on the iPod touch. Are they downloaded externally and then added to your iTunes library? When you do a Get Info on one of those episodes, on the Summary tab, what does it say for Kind, Format, Size, and Bit Rate?
I assume there is no problem when you play podcasts downloaded in iTunes on the iPod touch. That is why there is no problem when you first convert a podcast to AAC and then load it on the iPod touch.

Thanks for the reply
If I right click on the one in the music section of iTunes it says do I want to edit mulipile items and already shows it as a podcast. so it must be linking the two files together in some way
As for the properties of the files they are
Kind MPEG Audio file
Format MPEG1 Layer 3
Size 12.9mb (~for about half an hour)
Bir rate 64kps
Sample rate 44.100kHz
They are downloaded by iTunes using a link from the BBC site to create the subscription
I've not tried and other iTunes podcasts
Podcats list 'correctly' in date order on both the nano and touch but when the nano is plugged into the car it's alphabetical as I think it just reads it as a file USB system ?
As for creating playlists I could beut this seems like alot of hassle for something that already lists correctly on the devices
Oh by the way to state the obvious if you hadn;t realised these same podcast files play fine on my now sold 2nd gen nano
Thanks again for you help
As a further FYI... Are you looking at the item's Genre? The Genre setting for an item may be "podcast," but that is not its media type categorization. Make sure you go to the Options tab of the Info window, and look at the Media Kind setting. If it is currently appearing in iTunes in the music library, Media Kind for that item is Music. Change it to Podcast and it will appear in the podcasts library.
There is nothing unusual about the file type. There should be no problem. And they are not somehow corrupted, since they play properly in iTunes and on the nano.
The only possible cause I can think of is that the iPod touch has data corruption in its storage, so that anything new that you try to load on it creates corrupted files (on the iPod touch); that causes the iPod's software to have problems accessing those files for playback, which results in the "skip and stutter." You can test this "theory" by loading some other NEW content (such as other podcasts or songs), in about the same quantity as the BBC podcasts, to see if the problem recurs. (Content that is already on the iPod touch may play fine, because it was loaded before the problem occurred.)
If that is the cause, the solution is to do a Restore on the iPod touch using iTunes. This will erase the iPod, reinstall its software, and set it to default settings. This will also resolve a problem related to the iPod's software or settings.

I tried a couple of things but no luck so am now trying a restore. iTunes downloaded 5.1.1 and extracted it but in now stuck on "Preparing iPod to restore" and i've now tried three times and eventually get error 1604 unkown error. How do I get out of this loop ??

OK a restart of the computer seems to have done the trick
I've transferred some files across and they see to work much btter
I hardly had any apps on it only iPlayer and taptalk
I restoreed as new device so it was empty
What sort of things can corrupt the file system so quickly ?
It was a used iPod touch, so did you do a Restore on it after you received it? If you initially connected it and synced it to your computer's iTunes library, that may erase the existing content, but that is not the same thing as doing a Restore. If there was existing data corruption on the iPod, or if it had issues with software or settings, they would remain.
If you did a Restore after receiving it, I don't know what caused the problem. As long as the hardware is not faulty, you should be fine after the Restore, like when that iPod touch was new.
