Known Issues

  • In LinuxMCE 0710b3 this file has DOS carriage return characters at the end of its lines. Before the script can be successfully run, those characters need to be edited out using a text editor such as vi
  • In LinuxMCE 0710b3 running this script results in each digit of the requested channel number being blasted 4 times in sequence; thus not actually transmitting the correct channel request.
    • I do not think this is correct. There are indeed DOS carriage returns, but I have been using this script in the external channel change command for several weeks, without one missed channel change, and the script is unmodified on my MD. I have not seen any problems with duplicate digits. My wife watches a lot of live tv from MythTV and she has not been complaining about problems changing channels. Can someone please confirm if these are indeed issues?--Rwilson131 22:46, 15 February 2008 (PST)
