mipsel & mips32el.ipk are compiled for receivers, not ubuntu. You would need to use 7-Zip to unpack the .ipk then send then TSPanel folder to \usr\lib\enigma2\python\Plugins\Extensions.
Even if you managed to get it installed, all the files that are hosted on these addons panels will be mipsel/mips32el format, so it will be of no use to you.
So in other words, I won't work?? :((
Even if i try to use iptv with it??
Well I do have an DM500s which is just laying around and dusting, do you think that it will work it that?
