Windows 7 - Can I delete Audio_Ts and Video_Ts Files?

Hello,
I removed content from a DVD and saved to Audio_TS and Video_Ts files. These files were saved in my documents, to burn a DVD. Converted the files to DVD, then had the excess files, (Audio_Ts and Video_Ts), along with an empty Ts folder. Now that these files have been converted to Mpeg, can I delete them? The BUP files were also part of these files. I see no need to keep these files, once the conversion has completed. Any and all information is appreciated.

If they are converted in mpeg, there is no need to keep the other files and folders. Even the decrypted files from a DVD can be run smoothly using the .vob files only.

Thank you very much Arc. I did delete all files. Your assistance is truly appreciated.
