IPod Touch - 2 problems

Question

This is my first post on the forum, and I'm reasonably new to using an iPod-iTouch.
I have an iTouch 4th Gen 64G
Running on an old PC (3.4Ghz P4, 768M ram) using iTunes 10.6.x (version before exisiting 10.7).
1 I had a problem when my iTouch was running IOS 5.0.1 in that whilst it worked OK and I could upload from iTunes, uploading and syncing took an age. Minutes sometimes to create a playlist and sync it onto the iTouch. From looking around on the web in google it appeared quite a few folk had seemed to have this issue, both with syncing and backing up taking a while when you first connect the iTouch to iTunes, but also when you sync any changes. A lot of posts seemed to suggest an update was coming to fix this with "wait for 6" type comments. I continued to be frustrated but carried on using the device and built up a reasonable list of music and video (in playlists (see point 3)) on the device, awaiting IOS 6.
2 IOS6 arrived and I updated. I first called Appple support via the web site, and they issued a ticket number and called back. My query was basically "Will upgrading an iTouch from IOS5 to IOS6 damage or erase my data already on the iTouch in anyway". I was told "No, not at all". Emboldened, I connected my iTouch to iTunes and went for the IOS6 update. After a while, 30 minutes or so, it was completed and I was on IOS6.
However, the speed issue had not been helped in anyway. Its still as slow as ever. I used to have an iPod classic which failed hence the iTouch. On the same machine it was fast, very fast in comparisson, although it used its much older iTunes probably 6.x ot 7.x - can't remember.But it seems strange to me that an old hardware device using a hardrive should be much quicker than a new device using solid state. Surely somethings afoot here?
3. Now I get to the other point. On IOS5, my videos were in playlists and seperated as required. So maybe (for example) Holiday video 2010 was in one playlist, Holiday video 2011 was in another playlist, and Holiday Video 2012 in yet another. i.e. all easy to get at and all seperated from each other. After the upgrade to IOS6 the playlists still show on the iTouch, but all appear empty, and all the videos have been dumped into one folder (Entertainment icon - video). Also whereas before I could play them with the music player, now I can't, I have to use the video player. And the Music player allows portrait/lanscape viewing as the iTouch is tilted which is great for some videos, the video player does not, its stuck in landscape.
So the basic questions:
1 - Why is this iTouch so slow, and how can this be corrected? (I guess I have some vital switch option incorrectly set - maybe?)
2 - How do I get the video back into playlists on the iTouch? (The playlists are all still in place in iTunes, and a 'sync' didn't help).
Sorry its a long first post, but hopefully not too long.
Thanks (in advance)

Answer 1

Also, just noticed my pictures are all mixed up as well
They were arranged in numbered sections for type; i.e. cars, motorbikes, country side views, etc,
BUT, after the upgrade the pictures are all there but in mixed order. So in iTunes the pics are still in number order groups, but on the touch they are all mixed together.
Have I missed something silly? Is there a view - order type function?
(Begining to wish I'd waited for the first IOS6 bug fix )
Sorry but this has got a bit drawn out so as a reminder:
1 - Why is this iTouch so slow, and how can this be corrected? (I guess I have some vital switch option incorrectly set - maybe?)
2 - How do I get the video back into playlists on the iTouch? (The playlists are all still in place in iTunes, and a 'sync' didn't help).
3 - Just found, why are the pictures jumbled on the touch and not as they were ordered before the update or how they still are in iTunes?
Thanks
