mencoder, dvd rip and problem with 2 CDs

I have a problem with mencoder (I suppose). I learned how to rip from the page http// (I'm not allowed to post any URLs, sorry for this inconvenience). I'm doing it as follows:

$ mencoder dvd://1 -ovc frameno -oac lavc -o frameno.avi
$ mencoder dvd://1 -o /dev/null -oac lavc -ovc lavc -lavcopts \
vcodec=mpeg4:vbitrate=[some_value]:vhq:vpass=1 -vop scale=720:480; \
mencoder dvd://1 -o test.avi -oac lavc -ovc lavc -lavcopts \
vcodec=mpeg4:vbitrate=[some_value]:vhq:vpass=2 -vop scale=720:480
After the first command mencoder tells me about bitrate and number of CDs (e.g. if I want to have a movie on two 700MB CDs I should use a bitrate given by this command).

My problem is that if I rip this way for 2 CDs I get one huge avi file. (I'd like to cut it with avidemux later, but this is not a problem.) When I'm trying to play this file (with avidemux), I get the message:

[mpeg4 @ 0x8e95cc0]ac-tex damaged at 31 15
[mpeg4 @ 0x8e95cc0]Error at MB: 721
[mpeg4 @ 0x8e95cc0]concealing errors

 error in FFMP43/mpeg4!
(there are more such errors; they are always at 721 MB)

If I rip for 1 CD all is OK. I get also no errors when I rip with -endpos (I set it to 5-6 minutes).

I'm new on this topic (last Sunday was my first time with mencoder and DVD ripping). I was looking for answers in the net, but I haven't found anything.

What am I doing wrong?

I never took the time to learn the ins and outs of mencoder - I have better things to do with my time. :P
Instead I opted to capitalize on what others know instead, so I installed AcidRip which uses mencoder for the encoding process. AcidRip lets you set all your options in a clear and easy way, and off you go. Thanks to our moderator Acid Kewpie for this fine tool.
