Valid Feed wrong date and missing episod

The date difference is normally caused by being in a different timezone from the feed (which gives the date and time in CEST). It happens quite a lot and I wouldn't worry about it.

More seriously, your feed is not readable and cannot be subscribed to. You have numerous instances of ampersands (&) which can mess up a feed as they indicate the beginning of a code sequence which is never completed.

Oddly enough both episodes appear in the Store OK but cannot be subscribed to: evidently the Store's software can cope with this but iTunes itself cannot.

The best solution is to go through the feed changing every ampersand to the word 'and'.

Incidentally your category - 'music' - should have a capital M - 'Music' - to be correct.

You have the code incorrectly - you have &amp - it is &

Frankly I'd replace it with the word 'and' if I were you.

You have the string '&amp' in numerous places and these will certainly render your feed unreadable. If you change each of them to 'and' it will remove that problem. I can't promise that something else won't emerge as an error once these are cleared, but probably you will be OK and in any case you need to do this to go forward.

The errors are minor - the feed can now be subscribed to in iTunes and the latest episode downloads.

As to the report: Lines 60 and 110 - the entries are too long and iTunes will presumably truncate them. You should shorten them.

Line 83 - I don't know what they are complaining about here, it looks OK.

Line 141 - you can ignore this.

It looks as if it does not recognize CEST. You could change it to the time difference from GMT:

<pubDate>Tue, 01 May 2012 01:00:00 +0200</pubDate>

Try changing the time to midday rather than 0100 - that should get you clear of the day change.

<pubDate>Tue, 01 May 2012 12:00:00 +0200</pubDate>

You'll have to wait for the Store to catch up.
