I have a Sony Memory Stick Duo Adapter with 1 GB Memory Stick Pro Duo insert. When I put in my DCR-TRV18 camera and switch it to Memory, I get Memory Stick Error on the screen

As a last resort you could copy the full card to a computer and then delete the pictures on the card and use that again.

Here is the error list from the camera manual.
This is all I can suggest from here.

"Reinsert the Memory Stick Error"
•
Insert the "Memory Stick Duo" correctly.
•
The inserted "Memory Stick Duo"cannot be used in your camera
(See below).
•
The "Memory Stick Duo" is damaged.
•
The terminal section of the "Memory Stick Duo" is dirty

Your Sony uses a memory stick called Sony Memory Stick Pro which they don't make any more, it was replaced with a smaller card called Sony Memory Stick Pro Duo, go to ebay and buy a adapter called Sony Memory Stick Pro Adapter it is sliver in color with blue color at the end. Once you get ahold of that adapter, you can now buy the new smaller card called Sony Memory Stick Pro Duo and insert it to that adapter, then slide the adapter with the new smaller card into your camera.
I have several older Sony digital camera that I converted to use the newer Sony Memory Stick Pro Duo cards, it works great ! I checked your Sony model on Ebay and you have to scroll down a bit to see those adapters I just mentioned, some sell with the adapter and the newer memory stick already included in the price.

You probably need the old-style memory sticks, as this is a fairly old camera, or an adapter. See this article: http://en.wikipedia.org/wiki/Memory_Stick
Adaptors are cheap : http://www.ebay.co.uk/itm/Memory-Stick-Pro-Duo-Adapter-/251482939281?pt=UK_Photography_MemoryCardReaders_RL&hash=item3a8d8d1f91 is but one example, there are lots for sale out there or your sony shop may have one.
You may have to check to see if the camera is capable of reading and writing to a card of 4GB size, but as you have already bought it, it's worth a try.
Hope this helps.

check the small lock switch on the adapter usually located on the edge of the adapter. check and see if in lock or open position. if its in lock position toggle the switch to open position and you should be able to read as well as write date to and fro from the sony memory stick pro duo adapter. good luck

I am so sorry my friend, you have same problem as we all have, no memory bigger that 1 gb will work in cameras older than 3 years, I think yours is yes? the camera simply does not see those, sad I know, but that is how it is, I know because I have 3, yes 3 adaptors and 3 big mem bits here, and my money is lost.

Hello!

Following types of memory sticks are compatible with the Camera model DSC-V1:

Memory stick: 32/64/128 MB
Memory stick Pro: 256 MB/512 MB/1 GB/2 GB.
Mark 2 Memory stick Pro: 1/2 GB.

However, in order to use Memory Stick Duo or MagicGate Memory Stick Duo media with the Camera, a dedicated adapter (MSAC-M2) must be attached.

Follow the steps given below to troubleshoot the Camera that is not recognizing any compatible memory sticks:

http://www.kb.sony.com/selfservice/documentLink.do?externalId=C186797

Furthermore, you may try resetting the Camera to the original factory settings by pressing and holding the Reset button for 30 seconds.

If the issue persists even after performing all the above mentioned steps then the Camera is required to be diagnosed and serviced.

did you insert it in a correct location...?

Unfortunately, there is no way to change the internal card reader in the camera to accept higher density memory cards. You can find the memory stick compatibility list here: https://esupport.sony.com/perl/support-info.pl?&info_id=12 . Scroll down to the Cybershot N Series camera list. The maximum capacity memory stick is 4 GB memory stick pro or M2 Memory stick Pro. For the Memory Stick Duo, it looks like those have a maximum capacity of 2 GB.

I hope this helps.

On many cameras , the picture format that you can save on memory stick is not the same that you can have by recording on tapes. It should be tha same on your handycam.

You can increase memory stick to at least 2GB, that is what sony reccomends, you can test a 4 gb to 16 gb at the shop, if it works , then buy it.

However, the quality of movies grabbed on memory stick, should be far less than the one of movies recorded on tape.
