Sansa e250 i bought a sansa e250 and i have a micro sd and i whant to pass videos in to the sd card and still see them please answer.

The e250 uses microSD cards, not microSDHC cards. The maximum size of microSD cards is 2GB. Anything larger are microSDHC cards.

The Sansa only plays videos from its internal memory. You can put music on a microSD card, but not photos nor videos.

I expected to find the new playlists on the SD card as a separate file to access and play. Instead the SD card songs show on up the Sansa menu simply added among the existing songs / artists stored in the Sansa. Its not a solution but they are there. Since using the SD card, my Sansa does databse refresh everytime it starts, whether SD card is in it or not.

The Sansa Media Converter (SMC) software is required to convert and transfer videos as appropriate to your Sansa or your microSD card.

The Sansa will only show photos and play videos from its internal memory, not the microSD card. You can put music on the card, but not photos or videos.

Check the Sansa tutorials at http://www.sandisk.com/Retail/Default.aspx?CatID=1468
to make sure you have followed all the steps first.

In my experience, every mp3 player/photo frame/etc with a card reader has a MAXIMUM memory limit for the type of card that it can read. It is possible that the Sansa player can only read 2GB Micro SD cards or smaller - and thisi nformation may not have been available when they printed the manual. If you have followed all instructions, and it still will not read the card, try switching to a 2GB Micro SD card.

I don't think that the sansa e250 supports sdhc cards these cards 4gb and up are only compatible with newer electronics

According to what I've read, you can double the original memory, but no more than that, so the max you can have on a Sansa e250 would be 4 GB (2GB internal memory and 2GB external memory). I also read that the micro SD cards holds
music only-no video.

Go to the knowledge base on the Sansa site and find this (chances are you have an SDHC card in an incompatible unit):
Sansa e200 - verify the version of the player.  To check, go to SETTINGS > INFO. 
              
For 01.xx.xx firmware (e200 version 1) - up to 2GB microSD cards 
For 03.xx.xx firmware (e200 version 2) - up to 16GB microSDHC cards 
NOTE: Firmware is not interchangeable. 

Sansa e200R - up to 2GB microSD cards 

Sansa e100 - supports SD cards up to 2GB 

If music won't load onto Micro Sd card:
1) go to settings
2) go to USB mode
3)change to MSC format

Now you're good to go.
