conflicting libraries?

Dear forum members,

I am trying to combine to separate programs, which I both 'stripped down' to their bare essentials to keep it as simple as possible for myself.
I want to combine the TVout program of Wayne and Layn LLC (http://code.google.com/p/arduino-tvout/downloads/list) and the MPU 6050 example code I found here: Usage | I2C Device Library.

I tried many things to combine both codes, but it seems like the TVout.h library and the wire.h library are conflicting or making use of the same libraries/code somehow. I would like to know what steps I could take, and what do you think is the problem?

If you need more information in order to help me, please ask! I appreciate the help!

[cosmetic hint]
Please modify your post, select the code part(s) and press the # button so it get tagged properly.
That makes it easier to read and see the difference between code and text between it.

It might might it a little bit easier to get steps to resolution if you state what the actual problem is. As in, what kind of error messages are you getting or what behavior is occurring to suggest the code your wrote isn't working as expected?

oke, if I import the Wire.h library in the TVout program, it won't output anything on the tv screen, but it doesn't generate any error messages. But this happens already with just including the wire library.

The otherway around, when I implement the Tvout code in the MPU6050 program, the program still runs but gives funny values from the sensor and the TVscreen just stays black, but again no error messages from Arduino..

My first guess, without seeing your code, is that you are running out of memory.

ah yes perhaps you're right, I was also somehow a bit concerned about that too.. so then I would have to use two arduinos? or is there anything else I can try to get make better use of the memory I have?

or is there anything else I can try to get make better use of the memory I have?

I hate to sound like a broken record, but, without seeing your code, we can't help.
