DVD Studio Pro subtitle test

Hello I have a simple 3 line, 10 second subtitle test that I'm trying to make work and can't.

DVD Studio Pro 4.2.2
Mac Pro, 10.6.6
The subtitles have been made on a windows machine and saved as a text file. The message I get from DVD Studio Pro when I import the subtitle file onto the corresponding track's subtitle timeline is: No corresponding subtitles found.

The mpeg1 file time code starts at three minutes. (00:03:00:00)
The text file's first subtitle starts at three minutes: (00:03:00:00)
The timeline is set to show asset based timecode and starts at 3 minutes (00:03:00:00)
There are no fonts or styles specified (the text file is simply three subtitles)

I've attached the subtitle file 1824_testrastkowithtc.txt.zip
The mpeg1 file: 1825_avidtimecodempeg1.m1v.zip

As this was supposed to be a test for the longer subtitling process I need to know it's going to work, and I must be doing something wrong! Anybody know what's wrong?
Thanks.
Dan

Thanks Danny that worked
It was good to get at least a basic test working. Now I have to find out why the formatting is different when the subtitler exports their subtitle test.

is there a reason why you are using MPEG1 instead of MPEG2?

The subtitler's program only takes mpeg1 (I'll use MPEG2 for the final DVD)

your subtitel-file should look like that:
03:00:00:00, 03:00:10:00, sample-text

It worked!
Thanks.
