I can't seem to find any codes for the TX-1000. There are some posted for the dsm-320 and 520, but they only go up to the mx-850. My editor will not open the files because the tx-1000 uses files with a mxt extention while the 700-850 uses mxf and mxd. Of course I got the dsm-510 off ebay w/o a remote with the idea that I would not need it, so I can't use the learn function to program the remote. Any help would be greatly appreciated.
