Missing Channel in Package and Something Odd Happens

We have an old DVR (Comcast). Trying to watch Me Tv 357 takes you too the channel and them immediately "throws you out" of the DVR to a blue screen. Put another channel in the remote (501 Turner) "brings you back". Happens with channels in the 200 and 300's. 

Tried to reset DVR and several other things but no luck. Craziest thing I have seen...

Any ideas? We have held off on the X1 new DVR (actually sent it back becasue we hated the menu screen...be nice, now hahaha. It's so hard to read?

Thank you!
