1.20 issues still exists in 1.21 pre-release

I can confirm that these two problems exist in MP 1.21p (although I am using the internal build prior to the public pre-release build).

I have two "small" test files that I can provide if desired (where "small" means 26MB and 10MB for DVR-MS and WTV respectively).

Apologies; I did not intend to imply that I have a fix. I was offering a DVR-MS file and a WTV file to any of the developers who want to try to fix this (not everyone has leftovers from WMC). I don't have the skills needed to fix the problems that you found.

I've added this issue to Jira so it doesn't get forgotten - [MP1-4932] dvr-ms and wtv file types are treated differently in myVideos - Jira

 

I think that there may be another inconsistency:

(3) WTV and TS files show the programme synopsis on the info OSD (if XML files exist for them), but DVR-MS files do not (even if XML files exist for them). Note that all three filetypes show the programme synopsis on the list form of the "Videos" panel when the file has the focus.

I noticed this with my "ClassicWide" skin, but "DefaultWideHD" exhibits the same quirk.

The problem is that there are very few active developers working on MP1 now, and I think that MP2 is in the same situation. We all have things to do with our lives other than working on MP, and we must accept that some bugs will go unfixed, and some suggested improvements will go unimplemented.

I used Vista WMC for five years, during which I accumulated a large number of DVR-MS recordings. When I moved to MP in 2014, I too was disappointed to find that support for DVR-MS was worse than the support for TS (particularly not remembering the resume point). In the end I decided to convert all of my DVR-MS files to TS.

I happened to have a licensed copy of "VideoReDo", which can convert video DVR-MS to TS (but not audio-only DVR-MS to TS), so I used that to convert the TV recordings (but not the radio recordings). I wrote a bespoke tool to extract the metadata from the DVR-MS file and create the XML file that MP uses (so all of the converted files have the relevant info displayed in MP).

I never used Win7 WMC other than for testing, so I had no WTV files to convert. This was just as well, as I believe that it is only the "premium" version of "VideoReDo" that can convert WTV (not the version that I have), and my bespoke tool cannot extract the metadata from WTV files.

If you want to go the conversion route for a solution to this problem, you will need a tool to convert the files that you have (DVR-MS, WTV, audio-only), plus a tool to extract the metadata. There may now be freeware programs that will do this conversion (VLC would be the first one to investigate, although I found its conversion syntax to be incredibly obscure and difficult to understand). For the metadata, there is a tool by Stephen Toub that can display metadata (and I think that it works with WTV too), but I don't know whether it can be used in batch mode:
